| TEA5114A RGB SWITCHING CIRCUIT .25MHzBANDWI .CROSSTALK:55dB .SHORTCI .ANTISATURATI .VI TECTED DTH RCUIT TO GROUND OR VCC PRO- ON GAIN CHANGING DEO SWITCHING DIP16 (Plastic Package) ORDER CODE : TEA5114A PIN CONNECTIONS DESCRIPTION This integrated circuit provides RGB switching allowing connections between peri TV plug, internal RGB generator and video processor in a TV set. The input signal black level is tied to the same reference voltage on each input in order to have no differential voltage when switching two RGB generators. An AC output signal higher than 2 Vpp makes gain going slowly down to 0dB to protect the TV set video amplifier from saturation. Fast blanking output is a logicial OR between FB1 (Pin 8) and FB2 (Pin 10).
