Overview
The Nexperia 74HCT74BQ,115 is a dual positive edge-triggered D-type flip-flop in the 74HCT logic series. It features individual data (D), clock (CP), set (SD), and reset (RD) inputs for each of its two independent circuits. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 14-pin DHVQFN package with an exposed pad. It supports a maximum clock frequency of 59 MHz and exhibits a propagation delay of 60 ns.
Feature Summary
- Dual independent D-type flip-flops with positive edge triggering
- Asynchronous set and reset inputs for immediate state control
- Automotive qualification compliant with AEC-Q100 standards
Applications
- Digital signal processing systems requiring parallel data storage
- Automotive electronic control units (ECUs)
- Industrial communication interfaces
- General-purpose digital logic circuits
Procurement Notes
Verify that the specific part number suffix matches the required automotive grade and packaging configuration. Confirm compatibility with standard surface-mount assembly processes for the DHVQFN-14 package. Ensure supply chain sources provide valid traceability documentation consistent with Nexperia manufacturing standards.
Selection Notes
Select this component when dual D-type storage is required in a compact surface-mount footprint. The HCT technology ensures TTL-compatible input levels while operating at standard 5V logic supplies. Consider the exposed pad thermal design requirements inherent to the DHVQFN package for optimal performance.
Part Context
This component belongs to Nexperia's extensive portfolio of 74-series logic integrated circuits. The 74HCT family provides high-speed switching capabilities with robust noise immunity. The BQ suffix indicates the specific DHVQFN package variant designed for automated surface-mount assembly.
