74AHC74D,112

Overview

The Nexperia 74AHC74D,112 is a dual D-type edge-triggered flip-flop housed in a 14-SOIC package. It operates within a supply voltage range of 2 V to 5.5 V and supports a maximum clock frequency of 115 MHz. The device features set and reset functions with a propagation delay of up to 9.3 ns at 5 V. Output drive capability is specified at 8 mA for both high and low states, while static current consumption remains at 2 µA. It functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Dual positive-edge triggered D-type flip-flops with independent data, clock, set, and reset inputs
• Complementary outputs providing nQ and Q signals for each internal circuit
• Asynchronous active-low set and reset operations functioning independently of the clock signal

Applications

• Parallel-to-serial data conversion circuits
• Serial-to-parallel data conversion architectures
• Shift register configurations for data storage and transfer
• General-purpose digital logic state retention applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications regarding labeling or assembly updates. Ensure the specific suffix matches required packaging formats. Validate that the operating temperature range aligns with final system requirements before procurement.

Selection Notes

Select this component when dual flip-flops are required within a single package footprint. The wide supply voltage range allows compatibility with various logic families. Consider the 14-SOIC package dimensions for PCB layout constraints. Evaluate the 115 MHz speed against system timing requirements to ensure adequate performance margins for the intended application.

Part Context
