74ABT543CMTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT543CMTCX is an octal registered transceiver featuring 3-STATE outputs, housed 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 an ambient temperature range of -40°C to +85°C. The device provides bidirectional data paths with separate latch enable and output enable inputs for independent control. Propagation delay ranges from 1.5 ns to 6.5 ns depending on load conditions. Output current capabilities include sourcing up to 32 mA and sinking up to 64 mA.
