74HC74D-Q100HL

Overview

The 74HC74D-Q100HL is a dual D-type flip-flop integrated circuit from the Nexperia 74HC series, designed for automotive applications. It contains two independent positive-edge-triggered D-type flip-flops with set and reset inputs. The device operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 82 MHz. It features low static current consumption of 40 µA and offers complementary outputs. The component is housed in a 14-SOIC package (3.90mm width) and is qualified to AEC-Q100 standards, ensuring reliability across an operating temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability in vehicle electronics.
• Dual independent D-type flip-flops with dedicated set and reset control inputs for precise data handling.
• Wide operating voltage range supporting 2V to 6V power supplies for flexible system integration.
• High-speed performance capability with maximum clock frequency reaching 82 MHz.

Applications

• Automotive digital logic circuits requiring robust signal storage and synchronization.
• Data acquisition systems utilizing high-speed parallel or serial data processing.
• Industrial control interfaces needing reliable state retention under varying thermal conditions.

Procurement Notes

Verify the specific suffix HL against official Nexperia documentation to confirm package dimensions and marking details. Ensure compatibility with AEC-Q100 requirements if deploying in automotive environments. Cross-reference the part number with authorized distributors to avoid obsolete stock, as lifecycle status may vary by region. Confirm RoHS compliance status for regulatory adherence in target markets.

Selection Notes

Select this component when dual independent flip-flops are required in a compact SOIC package for automotive or industrial use. Compare propagation delay specifications at your target supply voltage against similar HC-series parts. Evaluate the 14-pin footprint constraints against your PCB layout. Consider the -40°C to +125°C temperature range suitability for harsh environments compared to commercial-grade alternatives.

Part Context

This part belongs to the 74HC74 family of dual D-type flip-flops. The Q100 designation indicates automotive qualification, while the D suffix specifies the SOIC package type. The HL suffix typically denotes specific tape-and-reel packaging or manufacturing lot variations defined by Nexperia. It serves as a fundamental building block for sequential logic in mixed-signal systems.

Replacement Considerations

Check for direct equivalents such as 74HC74D-Q100,118 from Nexperia, ensuring pinout and electrical characteristics match. Verify that alternative manufacturers' HC74 variants meet the same AEC-Q100 reliability standards and package dimensions before substitution.
