Description
Pericom Semiconductor’s PI5V331 is a true bi di rec tion al Dual
4-channel multiplexer/demultiplexer that is rec om mend ed for
both S-Video or composite video switching applications. e
switch can be driven from a current output RAMDAC or voltage
output composite video source.
Low On-resistance and wide bandwidth make it ideal for video
and other applications. Also this device has exceptionally high
current capability which is far greater than most analog switches
oered today. A single 5V supply is all that is required for opera-
tion.
e PI5V331 oers a high-performance, low-cost solution to
switch between video sources.

Notes:
1. For Max. or Min. conditions, use appropriate value specied under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, TA = 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between S1, S2, and D I/O pins at indicated current through the switch. On-Resistance is determined by the lower of the voltages
on the S1, S2, and D I/O pins.
