BH7634AS
The BH7634AS is one-chip IC that contains audio and video switches that support 21-pin SECAM and PAL connec-
tors.
The I2C BUS for switch control simplifies applications, while the two expansion ports allow up to two external inputs.
Applications
VCRs
Features
1) I2C BUS control.
2) Video input is sync tip clamped, and includes a
small-capacity (0.022µF) input capacitor.
3) Three FSCOUT values.
4) Two expansion ports.
5) Audio mute function.
6) 75driver output (pins 20 and 23) requires no
attached capacitor.
