74AHC573PW-Q100J

Latches Overview

The Nexperia 74AHC573PW-Q100J is an octal D-type transparent latch with 3-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerance up to 5.5 V. It includes latch enable (LE) and output enable (OE) controls, ensuring high noise immunity and CMOS low power dissipation.

Latches Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Wide supply voltage range from 2.0 V to 5.5 V
• Overvoltage tolerant inputs to 5.5 V
• All inputs have Schmitt-trigger action

Latches Applications

• Automotive applications
• Mixed voltage environments
• Data storage registers

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with system voltage levels and interface requirements before integration. Confirm that the component meets all necessary automotive reliability standards for the intended application environment.

Latches Selection Notes

Select this component for designs requiring octal data latching with 3-state output control in automotive or industrial environments. Consider the TSSOP20 package for space-constrained PCB layouts. Verify input voltage levels match the source logic family, as the AHC variant requires CMOS levels while AHCT accepts TTL levels.

Latches Part Context

This part belongs to the Nexperia 74AHC_AHCT573_Q100 series of octal D-type transparent latches. It shares functional characteristics with other members of the series but differs in package options such as SO20 and DHVQFN20. The PW suffix specifically denotes the TSSOP20 plastic thin shrink small outline package.

Latches Replacement Considerations

Direct substitutes include other 74AHC573 variants from Nexperia with different packages, such as 74AHC573D-Q100 (SO20) or 74AHC573BQ-Q100 (DHVQFN20). Cross-brand replacements must match the octal latch functionality, 3-state outputs, and AEC-Q100 qualification if automotive use is required.
