74FCT16543ATPAG8

Buffers, Drivers, Receivers, Transceivers Overview

The 74FCT16543ATPAG8 is a 16-bit latched transceiver manufactured by Renesas Electronics Corporation. It utilizes 0.5 micron CMOS technology and operates at a core voltage of 5V. The device features a typical output skew (tSK(o)) of less than 250ps, serving as a high-speed, low-power replacement for ABT functions. It is housed in a TSSOP-56 package with a length of 14mm and contains 56 lead counts. The component is designated as obsolete and no longer manufactured.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Engineers must confirm the authenticity of existing stock due to the end-of-life status. Design-in activities are discouraged; migration to alternative solutions is recommended for new projects.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Selection of this part is restricted to maintenance of existing designs where redesign is not feasible. Users should evaluate the long-term supply chain risks associated with obsolete components. Alternative devices from other manufacturers may offer similar pinouts and electrical characteristics but require thorough validation of timing parameters and voltage levels before integration into critical systems.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74FCT16543ATPAG8 belongs to the 74FCT logic family, which bridges the performance gap between standard TTL and advanced CMOS technologies. This specific model provides latched bidirectional data transfer capabilities essential for complex digital systems requiring precise timing control and data integrity across wide buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Texas Instruments offers the 74FCT162543ATPACT as a potential substitute. Verification of electrical compatibility and pinout alignment is required before considering any cross-manufacturer replacement options.
