SN74ALVCH373ZQNR

Overview

The SN74ALVCH373ZQNR is an automotive-grade, octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features eight non-inverting inputs and outputs. The device provides low static current consumption of 20 uA and supports output drive currents of 32 mA (low) and -24 mA (high). Propagation delays are specified at 4 ns and 3.6 ns. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a BGA-Microstar-Junior-20 package.

Feature Summary

Automotive-grade qualification for enhanced reliability in vehicle applications
Low-voltage operation compatible with 1.65 V to 3.6 V power supplies
High-drive capability supporting 32 mA low-level and -24 mA high-level output currents

Applications

Automotive data bus systems requiring robust signal latching
Portable electronic devices utilizing low-voltage logic families
Industrial control interfaces needing high noise immunity

Procurement Notes

Verify the specific ZQNR suffix indicates automotive grade qualification and RoHS compliance before procurement. Confirm package availability as the component may be subject to end-of-life status or limited production runs. Ensure design compatibility with the BGA-Microstar-Junior-20 footprint and reflow soldering profiles suitable for this micro-package type.

Selection Notes

Select this component when automotive reliability standards are mandatory alongside low-voltage logic requirements. The ALVCH series offers superior speed and lower power consumption compared to standard HC or HCT counterparts. Consider the BGA package constraints for PCB layout density and thermal management during the selection phase.

Part Context

This part belongs to the SN74ALVCH373 family of octal transparent D-type latches. The ZQNR suffix specifically denotes automotive-grade manufacturing and packaging. It serves as a specialized variant designed for harsh environments where standard commercial-grade logic components may not meet durability or performance specifications required by automotive OEMs.
