... 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. ...
