Video signal switcher for AV amplifiers
BA7626 / BA7626F
The BA7626 and BA7626F are video signal switches that contain two five-channel analog multiplexers for switching
chroma and audio signals, and two wide-band 6dB amplifiers. By simply adding transistor buffers to the outputs, it is
possible to construct a record / playback switch for two record / playback VCRs, and three video playback machines
(eg. laser desk players). Input switching and VCR record switching can be done independently. The inputs are termi-
nated with 20k鈩?resistors, and are suitable for switching chroma and audio signals.
