High-performance Video Driver Series Standard 3-output Video Driver No.09065EAT04 BA7622F, BA7623F Description The BA7622F and BA7623F are video driver ICs with three built-in circuits, developed for video equipment. The three circuits in the BA7622F, two sync-tip clamp inputs and one bias input, are terminated by internal resistances of 20 k. The BA7623F output pins cab be connected directly in a DC coupling mode. Each output can drive 2 lines of load (75x2). Suitable to connect to a 2Vpp output type signal processing LSI and DAC. Features Common 1) 2 lines can be driven from each output 2) Can be operated by Vcc=4.5 V BA7622F 1) Large output dynamic range (3.3 Vpp, Vcc=5 V) 2) Built-in, 2 clamp input circuits and1 bias input circuit 3) Y signal, C signal, and composite video signal can be driven simultaneously by this particular IC. BA7623F 1) Wide output dynamic range (3.3 Vpp, Vcc=5 V) 2) Can be directly connected to previous stage circuit Applications TV, VCR, camcorder, and other video equipment.
