SN74ALVCH373DWR

Overview

The SN74ALVCH373DWR is an octal transparent D-type latch manufactured by Texas Instruments. It features a 20-SOIC package and operates within a supply voltage range of 2.5 V to 3.6 V. The device provides tri-state outputs with a maximum low-level output current of 24 mA. It supports bus-oriented applications and includes level-shifting capabilities for mixed-voltage systems.

Feature Summary

• Provides eight transparent D-type latches with tri-state outputs for bus-driven architectures
• Supports mixed-voltage operation through internal level-shifting between 3.3-V and 2.5-V domains
• Features high-impedance states when the output enable pin is asserted, reducing power consumption

Applications

• Bus-oriented memory mapping in embedded systems
• Clock data registers for synchronous data handling
• Mixed-voltage interface circuits requiring level translation

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure compatibility with RoHS standards and check for any recent product change notifications that may affect material composition or manufacturing location before finalizing procurement plans.

Selection Notes

Select this component for designs requiring reliable data storage in 3.3-V logic environments. Consider its low static power consumption and robust output drive capability compared to standard CMOS alternatives. Evaluate thermal performance within the SOIC-20 footprint constraints for dense PCB layouts.

Part Context

This part belongs to the ALVCH series, designed for low-voltage CMOS applications. It serves as a key component in digital logic families offering improved speed and lower power dissipation than legacy LS or HC counterparts, specifically optimized for 3.3-V systems.
