SN74ALVCH162260DLR

Overview

The SN74ALVCH162260DLR is a 12-bit to 24-bit multiplexed D-type latch designed for 1.65-V to 3.6-V VCC operation. It features tri-state outputs and addressable data latching. The device operates within a temperature range of -40°C to 85°C. It utilizes a 56-pin SSOP package with a width of 0.295 inches (7.50 mm). The component supports standard CMOS logic levels and includes overvoltage protection on inputs.

Feature Summary

• Multiplexes 12 input bits into a 24-bit output configuration via address control
• Provides tri-state outputs for bus-driven applications
• Supports low-voltage supply ranges from 1.65 V to 3.6 V

Applications

• High-density memory interface circuits
• Addressable data storage in communication systems
• Bus-oriented multiplexing architectures

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging variant rather than tube packaging. Confirm RoHS compliance status matches current regulatory requirements. Check lifecycle status as components may transition to obsolescence. Ensure the 56-SSOP footprint matches the target PCB design constraints.

Selection Notes

Select this component when a single IC must handle 12-bit data selection for a 24-bit bus. Compare propagation delay specifications against system timing requirements. Evaluate power consumption at the intended operating voltage. Consider pin count compatibility with available surface-mount assembly processes.

Part Context

This part belongs to the Texas Instruments 74ALVCH series, which offers advanced low-voltage CMOS technology. The ALVCH family provides high-speed performance with reduced power dissipation compared to older logic families. The 162260 variant specifically addresses multiplexing needs in wide-bus systems.

Replacement Considerations

Check for SN74ALVCH162260DGGR as an alternative TSSOP package option. Verify functional equivalence with SN74ALVCH162260DL if tube packaging is required. Confirm pinout compatibility before substituting.
