74FCT162245TPV

Overview

The IDT74FCT162245TPV is a Fast CMOS 16-bit bidirectional bus transceiver from the FCT series. It integrates two independent 8-bit transceivers within a single 48-pin SSOP package. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports an extended commercial temperature range from -40 °C to +85 °C. It features balanced output drivers providing ±24 mA drive capability, which helps reduce system switching noise. The inputs are TTL-compatible, and the outputs provide true, non-inverted signals with three-state control.

Feature Summary

• Integrates two independent 8-bit bidirectional bus transceivers for efficient data routing
• Features balanced ±24 mA output drivers to minimize system switching noise
• Supports live insertion via power-off disable functionality on outputs
• Utilizes high-speed, low-power 0.5 micron CMOS technology

Applications

• High-performance memory buffer applications
• Clock drivers and buffering
• Cache memory systems
• Complex logic interconnections

Procurement Notes

Verify the specific suffix 'TPV' against the manufacturer's current datasheet to confirm the exact package variant (SSOP) and lead-free status. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm that the TTL input levels match the source logic family in the target design.

Selection Notes

Select this component when dual 8-bit bidirectional transfer is required with balanced drive strength. It serves as a replacement for older ABT logic families. Consider the 48-pin SSOP package constraints and the 4.5 V to 5.5 V operating voltage range during circuit design.

Part Context

This part belongs to the IDT 74FCT series of high-speed CMOS logic devices. The FCT line is designed to offer performance comparable to ECL while maintaining CMOS power efficiency. The 162245 variant specifically provides dual 8-bit configuration, distinguishing it from single 16-bit or octal variants in the same family.

Replacement Considerations

Cross-reference with other manufacturers offering 74FCT162245 equivalents. Verify pinout compatibility and electrical characteristics such as propagation delay and drive current before substitution.
