74FCT162543CTPACT

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT162543CTPACT is a 16-bit latched transceiver from the FCT logic series, manufactured by Texas Instruments. It features two independent functions, each handling 8 bits of data with true output polarity. The device utilizes CMOS technology and operates within a supply voltage range of 4.5 V to 5.5 V. It provides three-state outputs and supports TTL input and output levels. The component is housed in a TSSOP-56 package (PDSO56) and is rated for operation between -40°C and +85°C. Key electrical characteristics include a propagation delay of 6.5 ns, low-level output current of 64 mA, and high-level output current of -32 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides registered bus transceiver functionality with latched data storage capabilities for stable signal transmission.
• Features dual enable control allowing independent direction management for each of the two 8-bit functions.
• Supports high-drive capability with significant low-level and moderate high-level output currents.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus interfaces requiring latched bidirectional transfer.
• System memory mapping and address decoding circuits.
• Parallel data buffering in industrial control systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CTPACT' against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TSSOP-56 form factor. Check for end-of-life status or obsolescence notices prior to final design approval, as availability may be limited.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide latched transceiver is required with separate enable controls for each byte. It is suitable for applications needing fast switching speeds and robust drive strength. Compare against non-latched variants if data registration is not necessary, or against lower-pin-count options if space constraints exist.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the CY74FCT162543T family of 16-bit latched transceivers. It shares functional similarities with other FCT series devices but offers specific pinout and packaging configurations. The TSSOP-56 package allows for surface-mount installation, facilitating automated assembly processes in modern electronics manufacturing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include CY74FCT16543T and CY74FCT162543TPVCT. Verify pin compatibility and electrical parameters before substitution. Alternative manufacturers such as NXP offer comparable parts like the 74ABT16543, though logic family differences must be evaluated.
