TDA8374 Overview
TDA837x family The various versions of the TDA837x series are I2C-bus controlled single-chip TV processors which are intended to be applied in PAL/NTSC (TDA8374 and TDA8375) and NTSC (TDA8373 and TDA8377) television receivers. All ICs are available in an SDIP56 package and some versions are also available in a QFP64 package. The ICs are pin patible so that with one application board NTSC and PAL/NTSC (or...
