SN74LV373ANSR

Latches Overview

The SN74LV373ANSR is an octal transparent D-type latch manufactured by Texas Instruments. It features eight D-type latches with three-state outputs, designed for low-voltage CMOS operation. The device operates within a supply voltage range of 2 V to 5.5 V and supports data rates up to 200 MHz. It utilizes a 20-pin Small Outline (SOIC) package with a width of 7.5 mm. The component includes an active-low latch enable input and an active-low output enable input to control data transparency and bus driving states.

Latches Feature Summary

• Provides eight independent transparent D-type latches for parallel data storage
• Features three-state outputs to facilitate direct connection to system buses
• Supports wide supply voltage operation from 2 V to 5.5 V for compatibility with various logic families

Latches Applications

• Parallel-to-serial conversion circuits
• Bus-oriented memory mapping
• Register files in digital systems

Latches Procurement Notes

Verify the specific datasheet revision and ordering suffix against the manufacturer's current documentation. Confirm that the SOIC-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the RoHS status with regional compliance regulations before procurement.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for low-voltage applications. The LV series offers improved power consumption compared to older LS or ALS technologies. Verify that the 200 MHz maximum frequency aligns with the system clock speed. Consider the 2 V to 5.5 V operating range if interfacing with mixed-voltage domains.

Latches Part Context

This part belongs to the SN74LV373A family of octal transparent D-type latches. It is functionally similar to other industry-standard octal latches but optimized for low-voltage CMOS processes. The 'ANSR' suffix indicates the SOIC-20 package type and reel packaging format. It serves as a standard interface element for buffering and storing parallel data in digital logic designs.

Latches Replacement Considerations

Check for SN74LV373ANSRE4 or SN74LV373ANSRG4 as potential equivalents with different environmental compliance markings. Verify pinout compatibility with alternative manufacturers such as Nexperia or ON Semiconductor offering similar LV-series octal latches.
