74ABT16543CMTD

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16543CMTD is a 16-bit registered transceiver featuring 3-STATE outputs, housed in a 56-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 contains two sets of D-type latches for temporary data storage, providing bidirectional data paths with separate control logic for each byte. It offers current sourcing capability of 32 mA and sinking capability of 64 mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment against the 56-Lead TSSOP specification. Ensure compliance with RoHS directives and check for moisture sensitivity level requirements prior to assembly. Review datasheet electrical characteristics for operating conditions matching system design parameters.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit registered data transfer with independent byte control. Consider the 56-Lead TSSOP package for space-constrained surface mount applications. Evaluate the 4.5V to 5.5V supply voltage range and -40°C to +85°C operating temperature against environmental constraints. Assess current drive requirements against the specified 32 mA sourcing and 64 mA sinking capabilities.
