BA7644AN
The BA7644AN is a four-channel analog multiplexer with mute, designed for use in video cassette recorders. It fea-
tures a wide dynamic range, and wide operating frequency range, and is suitable for switching audio and video sig-
nals.
Applications
VCR, TV and audio signal switching
Features
1) 4-input / 1-output switches.
2) Built-in mute.
3) Wide operating supply voltage range
(4.5V to 13.0V).
4) Low power consumption (48mW Typ.).
5) Excellent frequency characteristics
(10MHz, 0dB Typ.).
6) Wide dynamic range (3.5VP-P Typ.).
7) High input impedance (20k
Typ.).
8) Low interchannel crosstalk
( – 65dB Typ., f = 4.43MHz).
