BA7612N / BA7612F
The BA7612N and BA7613F are three-channel analog multiplexers with built-in mute, 6dB amplifier and 75Ω driver.
The ICs designed for use in video cassette recorders, and feature a large dynamic range and wide operating fre-
quency range. All inputs are terminated with 20kΩ (Typ.) input impedance.
