74FCT162500ATPVG

Overview

The IDT74FCT162500ATPVG is an 18-bit registered bus transceiver from the 74FCT logic family. It features a 56-pin SSOP surface-mount package and operates with TTL-compatible input and output levels. The device supports bidirectional data transfer controlled by independent direction control signals. It functions within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with standard 5V CMOS systems while providing high-speed performance characteristics typical of the FCT series.

Feature Summary

• Integrates 18-bit data storage registers to capture and hold data at the receiver side before transmission.
• Provides bidirectional data flow capability between two buses under independent direction control.
• Features TTL-compatible inputs allowing direct interfacing with TTL-driven logic sources.

Applications

• High-density memory buffer applications requiring data registration
• Bidirectional data bus interfaces in computer architecture
• General-purpose 18-bit data routing in industrial control systems

Procurement Notes

Verify the specific suffix 'TPVG' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical fitment during procurement.

Selection Notes

Select this component when an 18-bit width is required for registered bus transactions. The registered nature distinguishes it from non-registered variants like the 74FCT162500, making it suitable for timing-critical applications. Verify that the 56-pin SSOP package aligns with available assembly capabilities and board space constraints.

Part Context

This part belongs to the Integrated Device Technology (IDT) 74FCT series, which bridges the speed of ECL with the ease of use of CMOS technology. The 74FCT162500 variant specifically addresses wide-bus applications, offering higher integration density compared to 8-bit or 16-bit counterparts in the same logical family.

Replacement Considerations

Check for equivalents such as the 74FCT162500ATPV without the G suffix, noting potential differences in lead-free status or tape-and-reel packaging. Other registered transceivers in the 74FCT family may serve as functional substitutes if pinouts and bit-widths match.
