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.
•^Applications
Video cassette recorders and televisions
•^Features
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.).
7) Wide dynamic range (3.5VP-P Typ.).
8) Low interchannel crosstalk
( – 65dB Typ., f = 4.43MHz).
9) DIP / SOP 14 pin package.
