74LVC74ADB,118

Overview

The Nexperia 74LVC74ADB,118 is a dual D-type flip-flop with set and reset functions, operating within a supply voltage range of 1.2 V to 3.6 V. It utilizes Schmitt trigger inputs for enhanced noise tolerance and supports positive-edge triggering. The component features asynchronous active-low set and reset inputs that function independently of the clock signal. Data transfer occurs on the LOW-to-HIGH clock transition, requiring stable input setup times. It is housed in a 14-SO package and complies with JEDEC standards for various voltage levels.

Feature Summary

• Dual D-type flip-flops with individual data, clock, set, and reset inputs
• Asynchronous active-low set and reset operations independent of clock
• Schmitt trigger action at all inputs for slow rise/fall time tolerance
• 5 V tolerant inputs enabling direct interface with TTL logic levels

Applications

• Parallel data storage and register applications
• Frequency division and counter circuits
• Shift register implementations
• Digital state machine control logic

Procurement Notes

Verify the specific suffix 'ADB,118' against official Nexperia documentation to confirm the exact SOIC-14 package variant and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow soldering profile requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual edge-triggered storage with dedicated asynchronous control is required. The wide supply voltage range and 5 V tolerance make it suitable for mixed-voltage systems. Verify that the propagation delay characteristics meet your system timing constraints compared to faster ALVC alternatives.

Part Context

This device belongs to the Nexperia 74LVC family, designed for low-voltage CMOS applications. It provides high-speed performance while maintaining low power consumption. The part integrates standard D-flip-flop functionality with additional set and reset capabilities, offering flexible control options for digital design architectures.

Replacement Considerations

The 74LVC74AD,118 serves as a functional equivalent without the 'B' suffix, potentially differing only in packaging or manufacturing lot details. Cross-reference with other 74LVC74 variants from different manufacturers if pinout and electrical specifications align.
