CY74FCT162543TPVCT

Overview

The CY74FCT162543TPVCT 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 a 56-pin SSOP package (PDSO56) with a 0.300-inch body length and 0.025-inch pitch. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of -40 °C to 85 °C. The outputs are three-state with series resistors, providing a maximum output current of 24 mA.

Feature Summary

• Provides bidirectional data transfer capability between buses and peripheral devices through registered storage.
• Features independent output enable controls for each direction, allowing flexible bus management.
• Includes master control for latch operations to synchronize data capture across all channels.

Applications

• High-speed data acquisition systems requiring latched input buffering
• Bidirectional bus architectures in industrial control environments
• Memory interface circuits needing registered data holding

Procurement Notes

Verify component authenticity against official Texas Instruments documentation. Confirm the specific ordering suffix matches the required package type and environmental compliance standards. Ensure the supplier provides valid traceability records for the FCT series logic family.

Selection Notes

Select this component when a 16-bit width with individual latching is required for bidirectional communication. The FCT technology offers CMOS compatibility with TTL input levels. Consider the 56-pin SSOP footprint for PCB layout constraints and verify thermal requirements for the specified operating temperature range.

Part Context

This part belongs to the CY74FCT162543T family of 16-bit latched transceivers. It shares functional characteristics with other members like the CY74FCT162543TPVC but differs in packaging configuration. The series is designed for high-performance digital applications requiring reliable data retention during transmission cycles.

Replacement Considerations

Public confirmed substitute part numbers include CY74FCT162543TSSOP and CY74FCT162543TTSSOP. These variants maintain identical electrical specifications and pinouts while offering alternative surface-mount package options.
