IDT74FCT162543ETPA

Overview

The IDT74FCT162543ETPA is a registered bus transceiver belonging to the FCT series, manufactured by Integrated Device Technology. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes CMOS technology and is housed in a PDSO48 package with a 0.50 mm pitch. It supports bidirectional data transfer with independent control for each direction. The component operates within an extended commercial temperature range from -40°C to +85°C and includes three-state outputs with series resistors.

Feature Summary

• Provides registered bidirectional data transfer capability across two independent 8-bit channels
• Features independent output enable controls for each direction to manage data flow
• Incorporates three-state outputs equipped with series resistors for signal integrity

Applications

• High-speed data routing in computer systems
• Buffering and driving bidirectional buses in industrial control equipment
• Data transmission interfaces in telecommunications infrastructure

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration. Ensure the procurement matches the required lead time and compliance standards. Confirm that the component meets the necessary environmental regulations for the intended deployment region. Cross-reference the manufacturer's latest documentation to validate current production status and availability constraints.

Selection Notes

Select this component when designing systems requiring registered bidirectional data transfer with independent channel control. It serves as a suitable replacement for older ABT family functions due to its high-speed performance and low power consumption characteristics. Consider the 0.50 mm pitch TSSOP package for space-constrained PCB layouts requiring dense pin configurations.

Part Context

This device is part of the FCT (Fast CMOS) logic family, designed to offer high-speed performance while maintaining low power dissipation. The FCT series is widely recognized as a modern replacement for earlier bipolar logic families, providing improved switching speeds and compatibility with standard CMOS voltage levels in digital circuit applications.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the same logic family or equivalent devices from other manufacturers. Verify pinout compatibility and electrical specifications before implementing any substitute components in existing designs.
