74ABT543CMTC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT543CMTC is an octal registered transceiver featuring three-state outputs. It incorporates two sets of D-type latches for temporary data storage in either direction. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. It provides a low-level output current of 64 mA and a high-level output current of -32 mA. The component functions as a non-inverting bus transceiver with propagation delay characteristics typical of the ABT logic series.
