Video Switch for Canal+
BH7636S
Description
Dimension (Units : mm)
The BH7636S includes two video switches, one for
clamp input and the second for bias input.
*
The I2C Bus for switch control simplifies applications,
while the two expansion ports allow up to two external
inputs.
Features
1) I2C-BUS control
*
2) Video input is sync-tip clamped
3) Three FSCOUT
4) Two expansion ports
5) Mute function (bias)
SDIP24
6) 75 driver output (pins 20 and 23) requires
no attached capacitor.
7) Low value input capacitor : 0.022µF
I2C-BUS is a trade mark of PHILIPS Inc.
