74LVC374AD,118

Overview

The Nexperia 74LVC374AD,118 is an octal D-type flip-flop with 3-state outputs belonging to the 74LVC logic family. It operates within a supply voltage range of 1.2V to 3.6V and features Schmitt-trigger inputs for noise immunity. The device provides eight independent D-type flip-flops with positive-edge triggering. Key electrical parameters include a maximum propagation delay of 7.5ns at 50pF load, output drive currents of ±24mA, and operation across a temperature range of -40°C to +125°C. It is housed in a 20-pin SO package.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops with positive-edge clock triggering
• Three-state outputs allowing direct bus connection without additional interface hardware
• Schmitt-trigger inputs on all channels to enhance noise immunity and signal integrity

Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching of address or data buses
• General-purpose register implementations in embedded systems

Procurement Notes

Verify the complete ordering code including the suffix (e.g., 118) to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free solder plating requirements against specific project standards. Cross-reference the manufacturer part number with official Nexperia documentation to validate pinout compatibility and thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component when an octal storage solution with low-voltage compatibility is required. The 74LVC series offers superior speed compared to standard LVC devices while maintaining CMOS power efficiency. Ensure the application voltage falls within the 1.2V to 3.6V range and that the required output drive current does not exceed 24mA per pin. Consider the SO-20 package dimensions for PCB layout constraints.

Part Context

This device is part of the 74LVC244A/374A family of high-speed CMOS logic ICs manufactured by Nexperia. It complements other components in the 74LVC series, such as buffers and gates, enabling mixed-function digital designs. The 74LVC374AD variant specifically addresses the need for parallel data storage with tri-state control in compact surface-mount packages.

Replacement Considerations

Compatible substitutes include the SN74LVC374AD from Texas Instruments and the MC74LVC374ADTR2G from ON Semiconductor. Verify pinout compatibility and electrical parameter equivalence, particularly regarding propagation delay and output current capabilities, before substituting.
