75Ω driver IC with 3 internal circuits

BA7622F

The BA7622F is a 75Ω driver-IC developed for use in video equipment. It includes three 75Ω driver circuis,two of

which have sync-tip clamp inputs.The other driver has a biased input terminated with a 20kΩ resistor.Each output

can drive two loads (75Ω × 2).

•Applications

Video cassette recorders, televisions and camcorders

•Features

1) Two built-in clamp circuits.

2) Simultaneous drive of Y, C and composite video sig-

nals possible.

3) Each output can drive two loads.

•Absolute maximum ratings (Ta = 25°C)
