74HC573D-Q100,118

Latches Overview

The 74HC573D-Q100,118 is an octal D-type transparent latch with 3-state outputs, manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and is qualified to AEC-Q100 Grade 1 standards for automotive applications. The device features latch enable (LE) and output enable (OE) inputs, allowing data transparency when LE is HIGH and storage upon the HIGH-to-LOW transition. Outputs assume a high-impedance state when OE is HIGH. It includes input clamp diodes for interfacing with voltages exceeding VCC.

Latches Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1
• Wide supply voltage range from 2.0 V to 6.0 V
• CMOS low power dissipation with high noise immunity
• Inputs and outputs on opposite sides of package for easy microprocessor interface

Latches Applications

• Input or output port for microprocessors and microcomputers
• Bus-oriented applications using 3-state non-inverting outputs
• Automotive electronic systems requiring Grade 1 qualification

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm that the component meets the required AEC-Q100 Grade 1 specification for the intended automotive application environment. Check for any recent datasheet revisions that may impact design parameters.

Latches Selection Notes

Select this component for designs requiring an 8-bit latch with 3-state bus compatibility in automotive environments. Ensure the operating voltage falls within the 2.0 V to 6.0 V range. Consider the SO20 plastic small outline package dimensions if board space is constrained. Verify ESD protection requirements against HBM and CDM standards specified in the datasheet.

Latches Part Context

This part belongs to the 74HC573-Q100 family of octal D-type transparent latches. It shares functional characteristics with the 74HCT573-Q100 variant but differs in input logic levels. The 'D' suffix indicates the SO20 package, while 'Q100' denotes automotive qualification. Other package options include TSSOP20 and DHVQFN20 within the same product family.

Latches Replacement Considerations

Direct substitutes include other 74HC573 variants from different manufacturers that meet AEC-Q100 Grade 1 specifications. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.
