74ALVCH162260DLRG4

Latches Overview

The SN74ALVCH162260DLRG4 is a 12-to-24-bit multiplexed D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 3.6V and features tri-state outputs with high drive capability of 24mA for both high and low states. The device utilizes an EPIC submicron process and provides B-port outputs with equivalent 26Ω impedance. It is housed in a 56-BSSOP package (0.295", 7.50mm wide) and supports an operating temperature range of -40°C to 85°C.

Latches Feature Summary

• Multiplexed architecture supporting 12-bit or 24-bit data configurations via external selection
• Tri-state outputs enable direct bus driving without additional buffers
• High output drive current of 24mA ensures signal integrity across loads
• EPIC submicron CMOS process technology for enhanced performance

Latches Applications

• Data acquisition systems requiring parallel-to-serial conversion
• Memory interface buffering in embedded controllers
• Portable instrumentation with low-voltage power constraints

Latches Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the 56-BSSOP package dimensions match your PCB footprint requirements. Ensure the design accounts for the 1.65V to 3.6V supply range to maintain specified electrical characteristics. Check for any obsolescence notices from Texas Instruments regarding this specific part number revision.

Latches Selection Notes

Select this component when a multiplexed latch solution is required to reduce pin count in 12-bit or 24-bit applications. It is suitable for designs needing high drive strength on tri-state buses. Consider the 56-pin package size relative to available board space. Verify that the input voltage levels are compatible with the system logic family being used.

Latches Part Context

This device belongs to the Texas Instruments 74ALVCH family, designed for low-voltage applications. It is part of the Widebus family, offering high-density integration. The SN74ALVCH162260 serves as a specialized latch for managing wide data paths efficiently in compact packages.

Latches Replacement Considerations

Direct substitutes include the SN74ALVCH162260DGGR in a TSSOP package. Verify pin compatibility and package dimensions before substitution. Other variants may differ in packaging or specific electrical tolerances.
