74HCT74D-Q100,118

Overview

The 74HCT74D-Q100,118 is a dual positive edge-triggered D-type flip-flop manufactured by Nexperia USA Inc. It features individual data (nD), clock (nCP), set (nSD), and reset (nRD) inputs, along with complementary nQ and nQ outputs. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports a wide operating temperature range from -40°C to +125°C. It is housed in a 14-SOIC package and complies with AEC-Q100 Grade 1 automotive standards.

Feature Summary

• Dual positive edge-triggered D-type flip-flop architecture
• Individual asynchronous active LOW set and reset inputs
• Complementary output configuration for versatile logic interfacing

Applications

• Automotive electronic control units requiring AEC-Q100 compliance
• Industrial automation and process control systems
• Data storage and shift register applications

Procurement Notes

Verify the specific suffix '118' against official Nexperia documentation to confirm tape and reel packaging specifications. Ensure the component meets the required AEC-Q100 Grade 1 qualification for your target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a dual D-type flip-flop with independent set and reset controls is required. The HCT logic family ensures TTL-compatible input levels, facilitating direct interfacing with legacy digital systems. Verify that the 14-SOIC package dimensions fit the available PCB footprint and that the operating temperature range aligns with the system's thermal constraints.

Part Context

This component belongs to the Nexperia 74HCT-Q100 series, which provides automotive-grade logic solutions. The series combines high noise immunity with low power dissipation, suitable for demanding environments. The 74HCT74 variant specifically addresses sequential logic needs within automotive and industrial design architectures.

Replacement Considerations

Compatible substitutes include the 74HC74D-Q100,118, though HC logic differs in input threshold characteristics compared to HCT. Other potential replacements within the same family may require verification of pinout compatibility and electrical parameter alignment.
