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) 75Ω driver output (pins 20 and 23) requires no
attached capacitor.
