CY74FCT162543TPVC

Overview

The CY74FCT162543TPVC is a 16-bit latched bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels with TTL output levels. The device features three-state outputs and is housed in a 56-pin SSOP package. It functions as a registered transceiver with independent output enable for each direction and master control for the latch.

Feature Summary

• Provides bidirectional data transfer between two buses with integrated latching capability
• Features three-state outputs to facilitate direct connection to system buses
• Includes independent output enable controls for each direction

Applications

• High-performance register banks
• Bus-oriented memory architectures
• Clocking circuits requiring data latching

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be limited. Ensure the SSOP-56 footprint matches the design requirements before procurement.

Selection Notes

Select this component for designs requiring 16-bit wide data paths with simultaneous latching. Verify that the 4.5 V to 5.5 V operating range aligns with the system power supply. Ensure the SSOP-56 package size fits the PCB layout constraints.

Part Context

This part belongs to the 74FCT logic family, which utilizes Fast CMOS technology. It is designed for high-speed applications requiring low power consumption. The device integrates both transceiver and register functions into a single package.
