General Description
The MAX9140/MAX9141 are single and the MAX9142/
MAX9144 are dual/quad high-speed comparators opti-
mized for systems powered from a 3V or 5V supply. The
MAX9141 features latch enable and device shutdown.
These devices combine high speed, low power, and
rail-to-rail inputs. Propagation delay is 40ns, while sup-
ply current is only 150µA per comparator.
The input common-mode range of the MAX9140/
MAX9141/MAX9142/MAX9144 extends beyond both
power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, mak-
ing these devices ideal for interface with both CMOS
and TTL logic. All input and output pins can tolerate a
continuous short-circuit fault condition to either rail.
Internal hysteresis ensures clean output switching, even
with slow-moving input signals.
The MAX9140/MAX9141/MAX9142/MAX9144 are high-
er-speed, lower-power, and lower-cost upgrades to
industry-standard comparators MAX941/MAX942/
MAX944.
The MAX9140 are offered in tiny 5-pin SC70 and SOT23
packages. The MAX9141 and MAX9142 are available in
8-pin SOT23 and SO packages, while the MAX9144 is
available in both 14-pin SO and TSSOP packages.

Note 4: VOS is defined as the center of the input-referred hysteresis zone. See Figure 1.
Note 5: The input-referred trip points are the extremities of the differential input voltage required to make the comparator output
change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis
zone. See Figure 1.

in shutdown.
Note 9: Specified between any two channels in the MAX9142/MAX9144.
Note 10: Specified as the difference between tPD+ and tPD- for any one comparator.
Note 11: Applies to the MAX9141 only for both SHDN and LE.

MAX9141
Detailed Description
The MAX9140/MAX9141/MAX9142/MAX9144 single-
supply comparators feature internal hysteresis, high
speed, and low power. Their outputs are pulled to with-
in 300mV of either supply rail without external pullup or
pulldown circuitry. Rail-to-rail input voltage range and
low-voltage single-supply operation make these
devices ideal for portable equipment. The
MAX9140/MAX9141/MAX9142/MAX9144 interface
directly to CMOS and TTL logic.
Most high-speed comparators oscillate in the linear
region because of noise or undesired parasitic feed-
back. This tends to occur when the voltage on one
input is at or equal to the voltage on the other input. To
counter the parasitic effects and noise, the MAX9140/
MAX9141/MAX9142/MAX9144 have an internal hystere-
sis of 1.5mV.
The hysteresis in a comparator creates two trip points:
one for the rising input voltage and one for the falling
input voltage (Figure 1). The difference between the trip
points is the hysteresis. The average of the trip points is
the offset voltage. When the comparator’s input volt-
ages are equal, the hysteresis effectively causes one
comparator input voltage to move quickly past the
other, thus taking the input out of the region where
oscillation occurs. Standard comparators require hys-
teresis to be added with external resistors. The
MAX9140/MAX9141/MAX9142/MAX9144’s fixed internal
hysteresis eliminates these resistors. To increase hys-
teresis and noise margin even more, add positive feed-
back with two resistors as a voltage divider from the
output to the noninverting input.
Figure 1 illustrates the case where IN- is fixed and IN+
is varied. If the inputs were reversed, the figure would
look the same, except the output would be inverted.
The MAX9141 includes an internal latch that allows
storage of comparison results. The L
—
E pin has a high
input impedance. If L
—
Eis high, the latch is transparent
(i.e., the comparator operates as though the latch is not
present). The comparator's output state is latched
when L
—
E is pulled low (Figure 2).
Shutdown Mode (MAX9141 Only)
The MAX9141 shuts down when the –
S
—
H
—
D
—
N
–pin is low.
When shut down, the supply current drops to less than
12µA, and the three-state output becomes high imped-
ance. The –
S
—
H
—
D
—
N
–pin has a high-input impedance.
Connect S
—
H
—
D
—
N
–to VCC for normal operation. Exit shut-
down with L
—
Ehigh (transparent state); otherwise, the
output will be indeterminate.
Input Stage Circuitry
The MAX9140/MAX9141/MAX9142/MAX9144 include
internal protection circuitry that prevents damage to the
precision input stage from large differential input volt-
ages. This protection circuitry consists of two back-to-
back diodes between IN+ and IN- as well as two series
4.1kΩresistors (Figure 3). The diodes limit the differen-
tial voltage applied to the internal circuitry of the com-
parators to be no more than 2VF, where VFis the for-
ward voltage drop of the diode (about 0.7V at +25°C).
For a large differential input voltage (exceeding 2VF),
this protection circuitry increases the input bias current
at IN+ (source) and IN- (sink).
Input Current = (IN+ - IN-) - 2VF
2 x 4.1kΩ
Input current with large differential input voltages
should not be confused with input bias current (IB). As
long as the differential input voltage is less than 2VF,
this input current is equal to IB. The output is in the cor-
rect logic state if one or both inputs are within the com-
mon-mode range.

Output Stage Circuitry
The MAX9140/MAX9141/MAX9142/MAX9144 contain a
current-driven output stage as shown in Figure 4.
During an output transition, ISOURCE or ISINK is pushed
or pulled to the output pin. The output source or sink
current is high during the transition, creating a rapid
slew rate. Once the output voltage reaches VOH or
VOL, the source or sink current decreases to a small
value, capable of maintaining the VOH or VOL static
condition. This significant decrease in current con-
serves power after an output transition has occurred.
One consequence of a current-driven output stage is a
linear dependence between the slew rate and the load
capacitance. A heavy capacitive load will slow down a
voltage output transition. This can be useful in noise-
sensitive applications where fast edges may cause
interference.
Applications Information
Circuit Layout and Bypassing
The high-gain bandwidth of the MAX9140/MAX9141/
MAX9142/MAX9144 requires design precautions to
realize the full high-speed capabilities of these com-
parators. The recommended precautions are:
1) Use a PCB with a good, unbroken, low-induc-
tance ground plane.
2) Place a decoupling capacitor (a 0.1µF ceramic
capacitor is a good choice) as close to VCC as
possible.
3) Pay close attention to the decoupling capacitor’s
bandwidth, keeping leads short.
4) On the inputs and outputs, keep lead lengths
short to avoid unwanted parasitic feedback
around the comparators.
5) Solder the device directly to the PCB instead of
using a socket.
