74LVC74AD,118

Overview

The Nexperia 74LVC74AD,118 is a dual edge-triggered D-type flip-flop featuring individual data inputs, clock inputs, and asynchronous active-low set and reset controls. It provides complementary outputs and utilizes Schmitt trigger action for improved noise immunity. The device operates within a wide supply voltage range of 1.2 V to 3.6 V, ensuring compatibility with various logic families. It supports partial power-down modes via I_OFF circuitry and offers robust ESD protection exceeding 2000 V HBM. The component is specified for industrial temperature ranges from -40 °C to +125 °C.

Feature Summary

• Dual positive-edge triggered D-type flip-flops with asynchronous active-low set and reset inputs
• Schmitt trigger inputs provide high tolerance for slow input rise and fall times
• I_OFF circuitry enables safe partial power-down operation by preventing backflow current
• Wide supply voltage range from 1.2 V to 3.6 V allows direct interfacing with TTL levels

Applications

• Parallel data storage in digital systems
• Shift register construction
• Timing delay circuits
• Frequency division applications

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's latest documentation to ensure correct package type and tape/reel specifications. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when dual independent D-type flip-flops are required in a compact surface-mount package. It is suitable for designs needing Schmitt trigger inputs to handle noisy environments or slow signal transitions. The wide voltage range makes it appropriate for mixed-voltage systems requiring interface between 1.2 V and 3.6 V domains without additional level shifting.

Part Context

This part belongs to the 74LVC family of advanced low-voltage CMOS logic devices. The 74LVC74A variant specifically provides dual D-type flip-flops with set and reset functions. It is designed for high-speed applications while maintaining low power consumption, fitting into standard SO14 packages for space-constrained PCB layouts.

Replacement Considerations

Direct substitutes include the 74LVC74APW and 74LVC74ABQ from Nexperia, which share identical logical functionality and pin configurations. Ensure that any replacement maintains the same package style and thermal specifications to fit existing board footprints.
