74HCT573DB-Q100J

Latches Overview

The Nexperia 74HCT573DB-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 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-compatible input levels, low power CMOS dissipation, and high noise immunity. It includes latch enable (LE) and output enable (OE) controls, with inputs on one side and outputs on the opposite side for easy microprocessor interfacing.

Latches Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• TTL-level input compatibility for direct interface with standard logic families
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Latches Applications

• Bus-oriented applications requiring 3-state non-inverting outputs
• Input or output ports for microprocessors and microcomputers
• Data storage and transfer in automotive electronic control units

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the component meets the required AEC-Q100 Grade 1 specifications for your target application environment. Cross-reference the full part number with official Nexperia databases to validate availability and revision status before finalizing procurement plans.

Latches Selection Notes

Select this component when TTL-compatible inputs are required alongside 3-state bus capabilities in automotive environments. The wide operating temperature range and robust latch-up performance make it suitable for harsh conditions. Consider the SO20 package dimensions and pinout configuration during PCB layout to ensure proper thermal management and signal integrity.

Latches Part Context

This component belongs to the Nexperia 74HCT573-Q100 series of octal D-type transparent latches. It shares functional characteristics with other variants in the family but is distinguished by its specific package and automotive qualification. The series provides reliable data storage solutions for digital systems requiring high noise immunity and low power consumption.

Latches Replacement Considerations

Direct substitutes include the 74HCT573PW-Q100 and 74HCT573BQ-Q100, which offer alternative package options such as TSSOP20 and DHVQFN20 while maintaining identical electrical specifications and automotive qualifications.
