75Ω driver IC with 3 internal circuits

BA7623F

The BA7623F is a 75Ω driver-IC developed for use in video equipment. Since the input is coming directly with no

bias at the base pin, the DC potential for the previous stage can be used for direct DC coupling. Each output can

drive two loads (75Ω × 2).

•Applications

Video cassette recorders, televisions and camcorders

•Features

1) Can be directly coupled to the previous circuit.

2) Each output can drive two loads.

•Absolute maximum ratings (Ta = 25°C)
