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.

Video cassette recorders and televisions

1) 5-input / 1-output switches.

2) Built-in mute (the IN5 pin can be use a mute input).

3) Sync-tip clamp inputs.

4) Wide operating supply voltage range

(4.5V to 13.0V).

5) Low power consumption (48mW Typ.).

6) Excellent frequency characteristics

(10MHz, 0dB Typ.).

8) Low interchannel crosstalk

( – 65dB Typ., f = 4.43MHz).

9) DIP / SOP 14 pin package.
