Video signal switcher
BA7649A / BA7649AF
The BA7649A and BA7649AF are five-channel analog multiplexers (the IN5 pin can be used a mute input) designed
for use in video cassette recorders. They feature large dynamic range, and wide operating frequency range, and
have sync-tip inputs which are ideal for switching video signals.
