Overview
Multimedia ICs 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.
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.
).
