Video signal switcher
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.
Applications
Video cassette recorders and televisions
Features
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.).
7) Wide dynamic range (3.5VP-P Typ.).
8) Low interchannel crosstalk
( – 65dB Typ., f = 4.43MHz).
