TA1201CNG
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA1201CNG
I C BUS CONTROL NTSC 1CHIP COLOR TV IC
TA1201CNG provides PIF, SIF, Video, Chroma and Deflection
circuit for NTSC Color TV. TA1201CNG also provides Audio-Video
Switch and Text interface. TA1201CNG combine these functions
in a 56pin dual-in-line shrink-type plastic package.
TA1201CNG realizes rationalization of various alignments and
controls by bus control system.
