IDT74FCT16543ETPAG8

Overview

The IDT74FCT16543ETPAG8 is a 16-bit latched bus transceiver manufactured by Renesas Electronics under the FCT logic series. It features two independent 8-bit transceivers with true outputs, housed in a 56-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It includes master control for latch functionality and independent output enable controls for each direction.

Feature Summary

• Provides bidirectional data transmission through two independent 8-bit channels
• Integrates latching capability controlled by a single master signal
• Features three-state outputs for effective bus line management

Applications

• High-speed data bus interfaces in computing systems
• Memory buffer applications requiring data retention
• I/O expansion circuits in embedded controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific suffix designations against current datasheets. Check for end-of-life notifications or obsolescence warnings prior to procurement planning to ensure long-term supply stability.

Selection Notes

Select this component when designing systems requiring simultaneous latched data transfer across wide buses. Ensure the application environment stays within the specified voltage and temperature limits. Verify that the TSSOP-56 footprint matches the PCB layout requirements and that the drive strength meets the load capacitance specifications of the connected circuitry.

Part Context

This part belongs to the 74FCT16543T family of registered bus transceivers. It shares functional similarities with other FCT series devices but is distinguished by its 16-bit width and integrated latch mechanism. The ETPAG8 suffix indicates specific packaging and environmental compliance attributes defined by the manufacturer.

Replacement Considerations

Cross-reference with IDT74FCT16543ATPAG8 or CY74FCT16543ATPACT for pin-compatible alternatives. Verify electrical parameter compatibility and package dimensions before substitution.
