SN74ALVCH162260GR

Overview

The SN74ALVCH162260GR is a multiplexed D-type addressable latch manufactured by Texas Instruments. It features 12-to-24-bit configuration options with tri-state outputs, designed for low-voltage operation between 1.65V and 3.6V. The device operates within a temperature range of -40°C to 85°C and utilizes a 56-TSSOP package. Key electrical characteristics include a propagation delay of 5.8 ns or 4.9 ns depending on conditions, quiescent current of 40 uA, and a low-level output current capability of 32 mA.

Feature Summary

• Multiplexed architecture allows flexible 12-bit or 24-bit data path configurations via external addressing.

Applications

• High-density memory interface buffering
• Data bus expansion systems
• Addressable latch applications in embedded controllers

Procurement Notes

Verify the specific datasheet revision (e.g., Rev. I) against your design requirements. Confirm that the 56-TSSOP footprint matches your PCB layout exactly. Ensure voltage levels align with the 1.65V to 3.6V supply specification. Check RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when bidirectional or unidirectional latching with addressable control is needed for wide data buses. The ALVCH technology supports mixed-voltage environments. Consider the 56-pin package density for space-constrained designs requiring high channel counts without increasing board area significantly.

Part Context

This part belongs to the Texas Instruments 74ALVCH series, which focuses on low-voltage CMOS logic solutions. The SN74ALVCH162260 specifically addresses the need for addressable latching in systems requiring data storage and controlled output enablement across multiple bits simultaneously.

Replacement Considerations

Check for SN74ALVCH162260DGGR as a potential alternative variant within the same family. Verify pin compatibility and electrical specifications before substitution. No other direct cross-references are confirmed in public documentation.
