74AHC573D-Q100J

Latches Overview

The 74AHC573D-Q100J is an octal D-type transparent latch with 3-state outputs, qualified to AEC-Q100 Grade 1. It operates on a supply voltage range of 2.0 V to 5.5 V. The device features balanced propagation delays and Schmitt-trigger inputs for high noise immunity. Inputs are overvoltage tolerant up to 5.5 V, allowing use as translators in mixed-voltage environments. It includes a common 3-state output enable input.

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating temperature range from -40 °C to +125 °C
• Overvoltage tolerant inputs enabling translation between mixed voltage levels
• Schmitt-trigger action on all inputs for improved noise immunity

Latches Applications

• Automotive electronic systems requiring robust logic latching
• Mixed-voltage interface circuits utilizing overvoltage tolerance
• Bus-oriented applications using 3-state outputs
• Microprocessor memory address latching

Latches Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm package type and tape/reel specifications. Confirm that the SO20 plastic small outline package (SOT163-1) matches the design requirements. Ensure compliance with RoHS and REACH regulations as stated in the product data sheet before finalizing procurement.

Latches Selection Notes

Select this component when automotive reliability (Grade 1) is required alongside standard CMOS logic performance. The wide supply voltage range supports both 3.3 V and 5 V systems. The overvoltage tolerant inputs simplify interfacing with higher voltage buses without additional level shifters. Verify thermal dissipation needs if operating near the upper temperature limit.

Latches Part Context

This part belongs to Nexperia's 74AHC/AHCT family of high-speed CMOS logic devices. The 'Q100' designation indicates automotive qualification. The 'D' suffix specifies the SO20 package variant. It serves as an 8-bit storage element within digital logic designs, providing transparent latching and tri-state control capabilities.

Latches Replacement Considerations

Check for direct equivalents such as the 74AHCT573D-Q100J if TTL-compatible input levels are preferred. Verify pinout compatibility with alternative manufacturers' octal latches. Ensure that any substitute also meets AEC-Q100 Grade 1 requirements if used in automotive contexts.
