SN74LVC573AQPWREP

Latches Overview

The SN74LVC573AQPWREP is an automotive-grade octal transparent D-type latch with tri-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input/output compatibility while powered by 3.3 V. The device features low static current consumption of 10 µA and offers high drive capability with low output impedance. It is designed for robust performance in harsh environments, supporting temperatures from -40°C to +125°C.

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for long-term availability and reliability.
• Supports mixed-mode signal operation enabling 5-V tolerant inputs on 3.3-V powered systems.
• Provides eight transparent D-type latches with shared latch enable and output enable controls.
• Features controlled baseline manufacturing with traceability to a single assembly and test site.

Latches Applications

• Automotive infotainment and display interface data buffering
• Engine control unit (ECU) I/O expansion modules
• Body control module data storage applications
• Industrial automation controller memory interfaces

Latches Procurement Notes

Verify the specific suffix 'REP' indicates the enhanced product configuration with controlled baseline and traceability requirements. Confirm that the package designation matches the required TSSOP-20 footprint for your PCB layout. Ensure the component meets the specific AEC-Q100 grade requirements for your target automotive application zone before finalizing procurement orders.

Latches Selection Notes

Select this component when designing for automotive environments requiring mixed-voltage logic interfacing between 5-V sensors and 3.3-V processors. The LVC series offers lower power consumption compared to standard HC or HCT families. Consider the tri-state output feature for bus sharing applications where multiple devices connect to a common data line without electrical conflict.

Latches Part Context

This part belongs to the SN74LVC573A-Q1 family of octal D-type latches. It shares functional similarities with the commercial SN74LVC573APWR but includes automotive-specific enhancements such as stricter quality control and extended temperature stability. The 'EP' designation signifies an enhanced product status intended for high-reliability applications.

Latches Replacement Considerations

Direct substitutes include the SN74LVC573AQPWRG4Q1 for general automotive use. For non-automotive commercial applications, the SN74LVC573APWR serves as a functional equivalent. Verify pinout compatibility and voltage tolerance specifications when cross-referencing with other octal latch variants from different manufacturers.
