Overview
Multimedia ICs Video signal switcher BA7602 / BA7602F The BA7602 and BA7602F are switching ICs developed for use in VCRs.
Each contains three two-channel analog multiplexers.
They feature a large dynamic range, and wide operating frequency range, and are suitable for switching audio and video signals.
Applications • Video cassette recorders and televisions Features • 1) Three 2-input / 1-output switches.
2) 5V power supply.
3) Low power consumption (70mW Typ.
).
4) Excellent frequency characteristics (10MHz, 0dB Typ.
).
5) Wide dynamic range (3.
1VP-P Typ.
).
6) High input impedance (20kΩ Typ.
).
7) Fast switching speed (50ns Typ.
).
