74FCT162501ATPVG

Overview

The IDT 74FCT162501ATPVG is an 18-bit registered bus transceiver from the 74FCT logic family. It utilizes a 56-pin SSOP surface-mount package and supports bidirectional data transfer with independent control for each direction. The device features TTL-compatible input and output levels, operating within a supply voltage range of 3.6 V to 5.5 V. Designed for industrial temperature applications, it provides high-speed data latching and transmission capabilities suitable for complex digital systems requiring reliable signal integrity.

Feature Summary

• Provides 18-bit registered data storage and bidirectional bus interfacing
• Features independent output enable controls for each transmission direction
• Supports TTL-compatible logic levels for seamless system integration
• Operates reliably across the full industrial temperature range

Applications

• High-density data bus interfaces in industrial control systems
• Memory address and data latching in embedded computing architectures
• Bidirectional communication links between microprocessors and peripheral devices
• Signal buffering and registration in telecommunications equipment

Procurement Notes

Verify the specific manufacturer source, as IDT assets are managed by Renesas Technology. Confirm that the component meets current environmental compliance standards required for your region. Ensure the SSOP-56 package dimensions align with your PCB footprint specifications. Validate the operational voltage range against your system power rails before finalizing procurement decisions.

Selection Notes

Select this component when an 18-bit width is required for registered bus applications. The 74FCT series offers faster switching speeds compared to standard CMOS alternatives. Consider the 56-pin SSOP package constraints regarding board space and thermal dissipation. Verify that the TTL input thresholds match the driving logic levels in your design architecture.

Part Context

This part belongs to the 74FCT (Fast CMOS) logic family, designed as a high-speed replacement for older bipolar technologies. The 162501 variant specifically integrates 18-bit registers with tri-state outputs. It is commonly used in systems requiring large data word transfers with precise timing control and synchronization capabilities.

Replacement Considerations

Check for equivalents such as the IDT74FCT162501CTPV or variants from other manufacturers like Texas Instruments offering similar 18-bit registered transceivers in compatible packages.
