General Description
Maxim’s MAX312L/MAX313L/MAX314L analog switch-
es feature low on-resistance (10Ωmax) and 1.5Ωon-
resistance matching between channels. These switches
are +3V logic compatible when powered from ±15V or
+12V supplies. The switches conduct equally well in
either direction, and offer low leakage over temperature
(2.5nA at +85°C).
The MAX312L/MAX313L/MAX314L are quad, single-
pole/single-throw (SPST) analog switches. The MAX312L
is normally closed (NC), and the MAX313L is normally
open (NO). The MAX314L has two NC switches and two
NO switches. All three devices operate from a single
+4.5V to +36V supply or from dual ±4.5V to ±20V, and
are available in 16-pin TSSOP, SO, and DIP packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Applications Information
Low-Distortion Audio
The MAX312L/MAX313L/MAX314L, having very low RON
and very low RON variation with signal amplitude, are
well suited for low-distortion audio applications. The
Typical Operating Characteristics
show Total Harmonic
Distortion (THD) vs. Frequency graphs for several signal
amplitudes and impedances. Higher source and load
impedances improve THD, but reduce off-isolation.
Off-Isolation at High Frequencies
In 50Ωsystems, the high-frequency on-response of
these parts extends from DC to above 100MHz with a
typical loss of -2dB. When the switch is turned off, how-
ever, it behaves like a capacitor, and off-isolation
decreases with increasing frequency. (Above 300MHz,
the switch actually passes more signal turned off than
turned on.) This effect is more pronounced with higher
source-and-load impedances.
Above 5MHz, circuit board layout becomes critical, and
it becomes difficult to characterize the response of the
switch independent of the circuit. The graphs shown in
the
Typical Operating Characteristics
were taken using a
50Ωsource and load connected with BNC connectors.
Power-Supply Sequencing-Free
Operation
Most CMOS switches require specific power-supply
sequencing in order to prevent the devices from latching
up. The older MAX312/MAX313/MAX314 devices require
a proper power-supply sequence of V+, VL, V-, and so
forth. Otherwise, it becomes necessary to add signal
diodes to the circuit in order to protect it from potential
latchups. The new MAX312L/MAX313L/MAX314L
devices eliminate the need for a VLpin and permit the
user to utilize any power-up sequence that is required. It
is, however, important not to exceed the absolute maxi-
mum ratings because stresses beyond the listed ratings
may cause permanent damage to the devices.
