74HCT74BQ-Q100,115

Overview

The 74HCT74BQ-Q100,115 is a dual D-type flip-flop with set and reset inputs manufactured by Nexperia. It belongs to the 74HCT logic series, ensuring compatibility with Low-power Schottky TTL (LSTTL) levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 47 MHz. It is housed in a 14-DHVQFN package measuring 2.5 x 3 mm. The component is qualified to AEC-Q100 Grade 1 standards for automotive applications and functions reliably across an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Dual D-type flip-flops with independent set and reset control
• AEC-Q100 Grade 1 qualification for automotive reliability
• TTL-compatible input levels via HCT logic family
• DHVQFN-14 package with side-wettable flanks for AOI

Applications

• Automotive electronic control units
• Data storage and shift register circuits
• Timing and synchronization systems
• Industrial process control logic

Procurement Notes

Verify that the ordering suffix matches the DHVQFN-14 package configuration and reel quantity specifications. Confirm the specific grade designation aligns with project requirements for automotive-grade components. Ensure the part number corresponds to the correct manufacturer documentation to avoid confusion with similar HC or standard HCT variants lacking automotive qualification.

Selection Notes

Select this component when TTL-compatible logic levels are required alongside high-speed performance. The HCT series ensures direct interfacing with LSTTL systems without additional level shifting. Consider the wide operating temperature range and robust latch-up performance for harsh environments. Verify pinout compatibility if replacing existing designs with non-automotive grade equivalents.

Part Context

This component is part of Nexperia's extensive portfolio of automotive-qualified logic integrated circuits. It complements other devices like the 74HC74BQ-Q100, offering HCT-specific input characteristics while maintaining the same physical footprint. The product line adheres to JEDEC standards, ensuring broad interoperability within digital logic design ecosystems requiring certified automotive reliability.

Replacement Considerations

The 74HCT74D-Q100,118 serves as a pin-compatible alternative in SOIC-14 packaging.
