74LVC374AD,112

Overview

The 74LVC374AD,112 is an octal D-type positive-edge-triggered flip-flop manufactured by Nexperia. It features 3-state outputs and operates within a supply voltage range of 1.2 V to 3.6 V. The device provides high noise immunity and low power consumption. It includes Schmitt-trigger action at all inputs for tolerance of slower rise and fall times. The component supports partial power-down applications via I_OFF circuitry, which disables outputs to prevent damaging backflow currents when the device is powered down. It complies with JEDEC standards for various voltage ranges.

Feature Summary

• Octal D-type positive-edge-triggered flip-flop with 3-state outputs
• Wide supply voltage operation from 1.2 V to 3.6 V
• Schmitt-trigger inputs for improved noise immunity
• I_OFF circuitry enables safe partial power-down mode

Applications

• Bus-oriented data storage in mixed 3.3 V and 5 V environments
• High-speed digital signal processing systems
• Portable battery-powered electronic devices
• Industrial control systems requiring robust noise tolerance

Procurement Notes

Verify the specific ordering suffix (e.g., 112) against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint and reflow soldering profile. Check for any recent Product Change Notifications (PCNs) regarding assembly or material changes. Confirm RoHS and REACH compliance status for your target market regulations before finalizing procurement.

Selection Notes

Select this component for applications requiring octal data latching with high-speed performance and low power consumption. The 1.2 V to 3.6 V operating range makes it suitable for modern low-voltage digital systems. Consider the 3-state output capability for bus sharing applications. Verify that the input voltage levels are compatible with your system's logic family, leveraging the Schmitt-trigger action for noisy environments.

Part Context

This part belongs to the 74LVC series of logic ICs, designed for low-voltage CMOS applications. It is functionally similar to other octal flip-flops but optimized for lower voltage operations compared to standard 5V TTL families. The AD suffix typically indicates a SOIC-20 package variant. It serves as a key building block for sequential logic circuits in consumer electronics and industrial automation.

Replacement Considerations

Direct substitutes include the 74LVC374PW,118 and 74LVC374APW,118 from Nexperia, which share identical logical functionality but may differ in package style or reel configuration. Cross-vendor equivalents such as the SN74LVC374AD from Texas Instruments offer pin-compatible alternatives. Always verify electrical parameters and package dimensions before substitution.
