74ALVC14PW,118

Overview

The Nexperia 74ALVC14PW,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 the supply voltage. Input capacitance is typically 3.5 pF, and power dissipation capacitance is 25 pF at 3.3 V.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for noise immunity
• IOFF circuitry prevents damaging backflow current during partial power-down
• Overvoltage tolerant inputs compatible with direct TTL level interfacing

Applications

• Signal conditioning for noisy environments requiring hysteresis
• Wave shaping of slow-rise-time digital signals
• Partial power-down mode operation in mixed-voltage systems

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component status remains active before finalizing design-in decisions. Ensure compliance with JEDEC standards relevant to the target operating voltage range. Check for any recent product change notices affecting assembly or marking details.

Selection Notes

Select this component when hex inverting functionality with Schmitt-trigger action is required. The TSSOP14 package offers a compact solution for space-constrained designs. Consider the propagation delay specifications relative to the system clock speed. Evaluate the power dissipation requirements against the thermal derating curves provided in the datasheet.

Part Context

This part belongs to the 74ALVC14 family of hex inverters. It is distinct from non-Schmitt variants like the 74ALVC04. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package. Other package options include SO14 and DHVQFN14 within the same logical family.

Replacement Considerations

Direct pin-compatible substitutes may include other hex Schmitt triggers from different manufacturers, but electrical characteristics must be verified. For Nexeria products, check if the 74LVC14 series meets the specific timing requirements, noting differences in drive strength and input thresholds.
