SN74LV373AZQNR

Latches Overview

The SN74LV373AZQNR is an octal transparent D-type latch with 3-state outputs designed for automotive applications. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode port operation across all ports. The device features low output impedance and is qualified under AEC-Q100 standards for high reliability in harsh environments. It includes Ioff support for partial power-down mode, allowing safe disconnection from the bus during power-off states without drawing excessive current.

Latches Feature Summary

• Automotive-grade qualification ensuring reliability in demanding vehicle environments
• Supports mixed-mode voltage operation on all ports for flexible system integration
• Enables partial power-down via Ioff functionality to minimize standby current consumption

Latches Applications

• Automotive infotainment systems
• Body control modules
• Instrument clusters

Latches Procurement Notes

Verify the specific suffix 'ZQNR' indicates automotive qualification and tape-and-reel packaging. Confirm RoHS compliance status and ensure the component meets AEC-Q100 requirements for your target application environment. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments documentation before finalizing procurement plans.

Latches Selection Notes

Select this component when automotive reliability and mixed-voltage interface capabilities are required. Ensure the operating temperature range aligns with your system's thermal design. Consider the package type availability and verify that the 3-state output characteristics match your bus architecture requirements for proper signal isolation.

Latches Part Context

This part belongs to the SN74LV373 family of octal latches. The 'A' denotes LV (Low Voltage) CMOS technology, while 'ZQ' signifies automotive qualification. The 'NR' suffix typically indicates a reel-based packaging format. It serves as a robust data storage element for digital interfaces in automotive electronics where standard commercial parts may not suffice.

Latches Replacement Considerations

Check for SN74LV373AQNR as a potential alternative if automotive qualification is still required but different packaging is needed. Verify pinout compatibility with existing PCB layouts before substituting. Ensure that any replacement maintains the same voltage levels and switching speeds to avoid timing violations in the circuit.
