74LVC374ADB,112

Overview

The 74LVC374ADB,112 is an octal D-type flip-flop with 3-state outputs from the Nexperia LVC series. It operates within a supply voltage range of 1.2 V to 3.6 V and features non-inverting logic. The device provides high noise immunity and overvoltage tolerant inputs up to 5.5 V. It is specified for operation across an extended temperature range of -40 °C to +125 °C. The component utilizes a 20-SOIC package and includes I_OFF circuitry to prevent damaging backflow currents during partial power-down applications.

Feature Summary

• Octal D-type flip-flop architecture with 3-state outputs
• Overvoltage tolerant inputs compatible with 5 V devices
• I_OFF circuitry for safe partial power-down operation
• Extended industrial temperature rating

Applications

• Parallel-to-serial data conversion
• Buffering and register storage in digital systems
• Clock domain crossing interfaces
• Mixed 3.3 V and 5 V logic translation environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel specifications. Confirm that the requested variant matches the required operating temperature range and output drive characteristics defined in the datasheet. Cross-reference the 12NC code with authorized distributors to guarantee authenticity and traceability. Ensure compliance with RoHS and REACH regulations as stated in the product environmental declaration.

Selection Notes

Select this component when an octal storage element with tri-state control is required in low-voltage designs. It is suitable for systems needing interface between 3.3 V and 5 V logic levels due to input tolerance. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the propagation delay and output current capabilities meet the timing and load requirements of the target application circuit.

Part Context

This part belongs to the 74LVC family of logic ICs, designed for low-voltage CMOS applications. It complements other octal buffers and latches in the same series, such as the 74LVC373 and 74LVC377. The LVC series emphasizes low power consumption while maintaining high speed and compatibility with standard logic families. It is widely used in portable electronics and battery-powered devices requiring efficient power management.

Replacement Considerations

Compatible substitutes include the 74LVC374AD,118 and 74LVC374D,112. These alternatives share identical logical functionality and pinout configurations. Verify package compatibility and electrical parameter equivalence before substitution. Ensure that any replacement part meets the same thermal and voltage specifications required by the original design.
