Pericom Semiconductor’s PI5V series of mixed signal video
circuits are produced using the Company’s advanced CMOS low
power technology achieving industry leading performance.
The PI5V331 is a true bidirectional Dual 4-channel multiplexer/
demultiplexer that is recommended for both S-Video or composite
video switching applications. The VideoSwitch™ 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
offered today. A single 5V supply is all that is required for operation.
The PI5V331 offers a high-performance, low-cost solution to
switch between video sources.

Notes:
1. For Max. or Min. conditions, use appropriate value specified 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. VOUT is the voltage across RL.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at Vcc = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V, control inputs only); S1, S2, and D pins do not contribute to Icc.
4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified
frequency. The S1, S2, and D I/O pins generate no significant AC or DC currents as they transition. This parameter is not tested,
but is guaranteed by design.
