SN74ALVCHR16269AR

Overview

The SN74ALVCHR16269AR is a registered bus exchanger from Texas Instruments' ALVC/VCX/A series. It supports 12 to 24-bit data paths and features true outputs. The device is housed in a 56-pin Plastic Dual Small Outline (PDSO) package, specifically TSSOP-56. It operates as a universal bus function component designed for high-speed data exchange applications within digital logic systems.

Feature Summary

• Registered bus exchange functionality for managing multi-bit data paths
• Supports variable bit-width configurations ranging from 12 to 24 bits
• Provides true output signal integrity for reliable data transmission

Applications

• Universal bus interface circuits
• Multi-bit data path management systems
• High-speed digital logic exchanges

Procurement Notes

Verify the specific suffix 'AR' against official Texas Instruments documentation to confirm the bulk packaging variant and temperature grade. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design, as minor suffix variations may indicate different package styles or testing conditions.

Selection Notes

Select this component when a registered bus exchanger with configurable bit-widths between 12 and 24 bits is required. The ALVC series offers low voltage operation suitable for modern digital interfaces. Confirm that the TSSOP-56 package dimensions fit the PCB layout constraints and that the true output polarity aligns with the downstream logic requirements.

Part Context

This part belongs to the Texas Instruments SN74ALVCH family of advanced low-voltage CMOS logic devices. The 'R' suffix typically denotes tape-and-reel packaging, while 'AG' variants may differ in package type such as TSSOP. This specific model focuses on bus exchange capabilities rather than simple buffering or latching functions.

Replacement Considerations

Check for SN74ALVCHR16269AGR which shares the same logical function but utilizes a reel package format instead of bulk. Verify pin compatibility and electrical characteristics before substituting.
