74HC74DB,112

Overview

The Nexperia 74HC74DB,112 is a dual positive-edge triggered D-type flip-flop with set and reset inputs, housed in an SSOP-16 package. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40 °C to +125 °C. The device features differential outputs and single-ended inputs, with a propagation delay of 17 ns at 5 V. Output currents are specified at 7.8 mA for both high and low states.

Feature Summary

• Dual positive-edge triggered D-type flip-flops with asynchronous active-low set and reset inputs
• Complementary Q and nQ outputs for flexible logic interfacing
• Schmitt-trigger action on clock input for tolerance to slow rise and fall times
• Inputs include clamp diodes enabling interface to voltages exceeding VCC

Applications

• Data storage and register applications
• Shift registers and counters
• Timing and synchronization circuits
• State machine implementations

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications via official Nexperia longevity programs. Ensure packaging integrity matches SSOP-16 specifications during receipt inspection.

Selection Notes

Select this component for designs requiring dual D-flip-flops with set/reset functionality in HC logic families. Verify voltage compatibility between 2 V and 6 V ranges. Consider thermal performance within the -40 °C to +125 °C operational window. Assess pinout compatibility with existing SSOP-16 footprints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It provides standard D-flip-flop functionality with additional control inputs. The DB suffix indicates the SSOP-16 surface-mount package variant. It is part of a broader family of compatible logic ICs designed for general-purpose digital applications.

Replacement Considerations

Check for equivalent parts such as 74HC74D,653 or 74HC74PW,112 from Nexperia. Verify pinout and electrical parameter compatibility before substitution. Consult official datasheets for any functional differences in set/reset timing characteristics.
