General Description

TDA8446 The TDA8446 is a video switch which has been designed for use in Digital Multistandard System Decoders (DMSD) in digital video system.

The device is intended for matrixing incoming RGB signals and for switching between luminance signals.

It generates a SYNC signal and TTL clamping pulses from any video signal with sync pulses.
