74ABT543CMTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT543CMTC is an octal registered transceiver featuring 3-STATE outputs in a 24-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of +4.5V to +5.5V and supports ambient temperatures from -40°C to +85°C. The device provides bidirectional data paths with separate latch enable and output enable inputs for independent control. Propagation delays are specified at 1.5 ns minimum and up to 10.5 ns maximum depending on load conditions.
