74HCT573D-Q100,118

Latches Overview

The Nexperia 74HCT573D-Q100,118 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 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL input levels, latch enable (LE) and output enable (OE) controls, and inputs with clamp diodes for overvoltage interfacing. It is housed in a SO20 plastic small outline package (SOT163-1).

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• TTL input levels ensure compatibility with standard logic families.
• High noise immunity and low power dissipation characteristics.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Latches Applications

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

Latches Selection Notes

Select this variant when TTL-compatible inputs are required for the 74HC573 family. Ensure the design accommodates the 4.5 V to 5.5 V supply range and the SO20 package dimensions. Confirm that the operating temperature requirements align with the specified -40 °C to +125 °C range for automotive environments.

Latches Part Context

This component belongs to the 74HCT573-Q100 series, which includes variants in different packages such as TSSOP20 and DHVQFN20. All variants share identical electrical specifications and functionality, differing only in physical package geometry and pinout arrangement. The 'D' designation specifically identifies the SO20 package version.

Latches Replacement Considerations

Direct replacements include other 74HCT573-Q100 variants from Nexperia in different packages, such as 74HCT573PW-Q100 (TSSOP20) or 74HCT573BQ-Q100 (DHVQFN20), provided the PCB footprint allows for package adaptation.
