74ALVC14D,118

Overview

The Nexperia 74ALVC14D,118 is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 3.6 V and includes IOFF circuitry for partial power-down applications. Propagation delay ranges from 1.0 ns to 5.1 ns depending on voltage conditions. Input capacitance is typically 3.5 pF, and the package is SO14 (SOT108-1).

Feature Summary

• Hex inverting Schmitt trigger configuration with six independent channels.
• IOFF circuitry prevents damaging backflow current during partial power-down mode.
• Overvoltage tolerant inputs allow direct interface with TTL levels without external resistors.

Applications

• Signal conditioning for noisy environments utilizing Schmitt-trigger action.
• Wave shaping of slow-rise-time signals into clean digital pulses.
• Partial power-down system designs requiring isolation of powered-off sections.

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm RoHS compliance status and REACH SVHC declarations against current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when hex inversion with hysteresis is required for noise immunity. Ensure the operating voltage stays within the 1.65 V to 3.6 V range. Consider the SO14 package dimensions if board space constraints exist relative to TSSOP or QFN alternatives.

Part Context

This component belongs to the 74ALVC logic family, characterized by high-speed operation and low power consumption. It serves as a standard digital logic gate solution for general-purpose signal processing in consumer electronics and industrial control systems requiring robust input thresholds.

Replacement Considerations

Public confirmed substitute part numbers include 74ALVC14PW,118 and 74ALVC14BQ,118. These variants share identical electrical specifications but differ in physical package form factors such as TSSOP14 and DHVQFN14 respectively.
