74AHC573BQ-Q100X

Latches Overview

The Nexperia 74AHC573BQ-Q100X is an octal D-type transparent latch with 3-state outputs, housed in a DHVQFN20 package (SOT764-1). 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. Static characteristics include low input leakage current and high noise immunity. Dynamic performance at VCC = 3.0 V to 3.6 V with CL = 15 pF shows typical propagation delays of 5.5 ns for data-to-output transitions.

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs enabling use as translators in mixed-voltage environments
• DHVQFN package with side-wettable flanks supporting automatic optical inspection

Latches Applications

• Automotive electronic systems requiring qualified logic components
• Mixed-voltage signal translation between different logic families
• Data storage and buffering in digital control circuits

Latches Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel sources genuine products matching the exact part number to guarantee compliance with automotive reliability standards and electrical parameters defined in the product data sheet.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for automotive or industrial applications operating between 2.0 V and 5.5 V. The DHVQFN20 package is suitable for space-constrained designs needing thermal enhancement. Verify that the CMOS input levels align with the driving source voltages, as this variant differs from the AHCT version which utilizes TTL input levels.

Latches Part Context

This device belongs to the Nexperia 74AHC573-Q100 family of octal D-type transparent latches. It shares functional similarities with other members of the series but is distinguished by its specific AHC logic family characteristics and the DHVQFN20 surface-mount package. The Q100 designation indicates automotive-grade qualification, differentiating it from standard commercial variants.

Latches Replacement Considerations

Direct replacements include other 74AHC573 variants in compatible packages such as SO20 or TSSOP20, provided pin compatibility is verified. Cross-family substitutes like 74HC573 or 74LVC573 may require voltage level adjustments due to differing input/output characteristics.
