BA7645N

The BA7645N is a four-channel analog multiplexer with mute, designed for use in video cassette recorders. It fea-

tures a large dynamic range, and wide operating frequency range, and has sync-tip inputs which are ideal for switch-

ing video signals.

Video cassette recorders and televisions

1) 4-input / 1-output switches.

2) Built-in mute.

3) Sync-tip 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).
