SN74ALVCHR16601G

Overview

The SN74ALVCHR16601GR is an 18-bit universal bus transceiver from the ALVCHR logic series, manufactured by Texas Instruments. It utilizes CMOS technology and operates within a supply voltage range of 1.65 V to 3.6 V. The device features 3-state outputs and is housed in a 56-pin TSSOP package. Key electrical parameters include a propagation delay of 6.3 ns, with high-level output current of -12 mA and low-level output current of 12 mA. It functions as a single circuit unit with independent control capabilities.

Feature Summary

• Supports bidirectional data transfer across 18 channels for universal bus applications
• Provides independent output enable control for each direction
• Operates reliably within industrial temperature ranges

Applications

• High-density memory interface systems
• Complex digital signal processing architectures
• Industrial communication bus networks

Procurement Notes

Verify the specific suffix 'GR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the component matches the required 56-pin TSSOP footprint and ALVCHR logic family specifications before integration into the design.

Selection Notes
