Video signal switcher for AV amplifiers
BA7625
The BA7625 is a video signal switch that contains two five-channel analog multiplexers and wide-band 6dB ampli-
fiers.It designed for use in video cassette recorders. By simply adding transistor buffers to the outputs,it is possible to
construct arecord / playback switch for two record / playback VCRs, and three video playback machines (eg.laser
disk players). Input switching and VCR record switching can be done independently. The BA7625 has sync-tip clamp
inputs which are ideal for switching video signals.
•Applications
AV amplifiers and video selectors
•Features
1) 5-input / 3-output switches.
2) Sync-tip clamp inputs.
•Absolute maximum ratings (Ta = 25°C)
