74LVC373ABQ-Q100X

Latches Overview

The Nexperia 74LVC373ABQ-Q100X is an octal D-type transparent latch with 3-state outputs, qualified to AEC-Q100 Grade 1. It features overvoltage tolerant inputs up to 5.5 V and a supply voltage range of 1.2 V to 3.6 V. The device includes IOFF circuitry for partial power-down protection and Schmitt-trigger inputs. Operating temperatures are specified from -40 °C to +85 °C and -40 °C to +125 °C. Propagation delays range from 1.5 ns to 18.2 ns depending on voltage. It utilizes a DHVQFN20 package (SOT764-1) with side-wettable flanks.

Latches Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• DHVQFN package with side-wettable flanks enables automatic optical inspection

Latches Applications

• Engine control units
• Body control modules
• Transmission control units
• Electronic instrument clusters

Latches Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration for automated assembly. Confirm that the DHVQFN20 package variant aligns with the PCB footprint design. Ensure the temperature grade meets the operational requirements of the target automotive environment. Cross-reference the AEC-Q100 qualification status with system reliability standards before finalizing component selection.

Latches Selection Notes

Select this component when designing mixed-voltage systems requiring translation between 3.3 V and 5 V logic levels. The wide supply range supports low-power applications down to 1.2 V. The high-impedance output state allows bus sharing in complex digital architectures. Consider the thermal performance of the DHVQFN package for space-constrained automotive board layouts.

Latches Part Context

This part belongs to the Nexperia 74LVC373A-Q100 family of octal latches. It shares functional compatibility with standard 74LVC373 devices but adds automotive-grade reliability and extended temperature specifications. The 'BQ' designation indicates the DHVQFN20 package type, while '-Q100X' denotes the specific automotive qualification and packaging format.

Latches Replacement Considerations

Direct substitutes include other AEC-Q100 qualified octal latches from Nexperia such as the 74LVC373AD-Q100 or 74LVC373APW-Q100, provided the package footprint differs. Non-Nexperia equivalents must be verified for pinout compatibility, electrical characteristics, and automotive certification status.
