Description
e PI3USB221E is a high-bandwidth switch specially designed
for the switching of high-speed USB 2.0 signals in handset and
consumer applications, such as cell phones, digital cameras, and
notebooks with hubs or controllers with limited USB I/Os.
e wide bandwidth (1.1 GHz) of this switch allows signals
to pass with minimum edge and phase distortion. e device
multiplexes dierential outputs from a USB host device to one of
two corresponding outputs. e switch is bidirectional and oers
little or no attenuation of the high-speed signals at the outputs.
It is designed for low bit-to-bit skew and high channel-to-channel
noise isolation, and is compatible with various standards, such as
high-speed USB 2.0 (480 Mbps).
e PI3USB221E oer over voltage protection for the D+/D- pins
as per the USB 2.0 specication. With the chip power on or o
if D+/D- pins are shorted to VBus (5V+/-5%), a less than 3.8V
(typical) signal will transmit through 1D+/1D- and 2D+/2D-
output.

Notes:
1. 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 under "recommended operating conditions" is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
2. All voltages are with respect to ground, unless otherwise specied.
3. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
4. VI and VO are used to denote specic conditions for VI/O.
5. II and IO are used to denote specic conditions for II/O.
6. The package thermal impedance is calculated in accordance with JESD 51-7.

1. VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins.
2. All typical values are at VDD = 3.3 V (unless otherwise noted), TA = 25°C.
3. For I/O ports, the parameter IOZ includes the input leakage current.
4. This is the increase in supply current for each input that is at the specied TTL voltage level, rather than VDD or GND.
5. Measured by the voltage drop between the input and output terminals at the indicated current through the switch. ON-state resistance is determined by the lower of
the voltages of the two terminals.
6. Dron is delta Ron between channels

Notes:
1. For Max or Min conditions, use the appropriate value specied under Electrical Characteristics for the applicable device type.
2. Specied by design
3. The switch contributes no propagational delay other than the RC delay of the on resistance of the switch and the load capacitance. The time constant for the switch
alone is of the order of 0.25 ns for 10-pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propaga-
tional delay to the system. Propagational delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and
its interactions with the load on the driven side.
