■ DESCRIPTION

The MB3863 is an IC motor driver with two independent reverse control functions. It drives motor drives of front-loading VTRs and auto-reverse cassette decks and stepping motors by reversible control at TTL and CMOS levels.

A heat protection circuit is incorporated to prevent damage by overheating.
