PI5V332
Low On-Resistance Wideband/Video
Quad with Individual Control
Description:
Pericom Semiconductor's PI5V332 is a true bidirectional Quad
Video Switch that is recommended for RGB, S-Video, or com-
posite video switching applications. The individual controls allow
for video, Hsync, or Vsync enable or disable. The 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 offered
today. A single 5V supply is all that is required for operation.
The PI5V332 offers a high-performance, low-cost solution to switch
between video sources.

Note:
Stresses greater than those listed under MAXIMUM RAT-
INGS may cause permanent damage to the device. This is
a stress rating only and functional operation of the device
at these or any other conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for ex-
tended periods may affect reliability.
Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V
CC
= 5.0V, T
A
= 25C 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 S
1
, S
2
, and D I/O pins at indicated current through the switch. On-Resistance is determined by the
lower of the voltages on the S
1
, S
2
, and D I/O pins. V
OUT
is the voltage across R

.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at V

4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The
S

, 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.
