74HC74BQ-Q100,115

Overview

The 74HC74BQ-Q100,115 is a dual D-type flip-flop with separate clock and clear inputs, manufactured by Nexperia. It operates within a supply voltage range of 2 V to 6 V and supports output currents of up to 7.8 mA in both high and low states. The device functions at temperatures between -40 °C and +125 °C, featuring static current consumption of 8 µA and operating power current of 160 µA. Packaged in a DHVQFN-20 format, it complies with AEC-Q100 Grade 1 standards for automotive reliability.

Feature Summary

• Dual D-type flip-flops with independent clock and asynchronous clear inputs
• Automotive-grade qualification compliant with AEC-Q100 standards
• Wide operating temperature range suitable for harsh environments

Applications

• Automotive engine control units
• Body control modules
• Transmission control systems

Procurement Notes

Verify the specific suffix '115' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the component meets AEC-Q100 Grade 1 requirements for your target automotive application. Cross-reference the DHVQFN-20 package dimensions with your PCB footprint library before finalizing procurement orders.

Selection Notes

Select this component when dual D-flip-flop functionality is required in space-constrained automotive designs. The DHVQFN-20 package offers a compact solution compared to traditional TSSOP or SO variants. Consider the 2 V to 6 V supply range compatibility with your system's logic levels and power architecture.

Part Context

This part belongs to Nexperia's 74HC series of high-cmOS logic devices, specifically designed for automotive applications under the Q100 qualification program. It provides standard D-type flip-flop functionality with enhanced noise immunity and low power dissipation characteristics typical of the HC logic family.

Replacement Considerations

Check for direct equivalents such as the 74HC74D-Q100 or 74HC74PW-Q100 if package changes are acceptable. Verify pinout compatibility and electrical parameter alignment before substituting with other manufacturers' automotive-grade dual D-flip-flops.
