74ALVC14BQ,115

Overview

The Nexperia 74ALVC14BQ,115 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.

Feature Summary

• Hex inverting Schmitt trigger configuration with six independent channels
• IOFF circuitry prevents damaging backflow current during partial power-down
• Overvoltage tolerant inputs allow direct interface with TTL levels
• High ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Partial power-down mode operation
• Signal conditioning with slow rise/fall times
• Direct interfacing with TTL logic levels

Procurement Notes

Verify the specific ordering suffix '115' corresponds to the DHVQFN14 package (SOT762-1) as defined in the official Nexperia datasheet. Confirm that the required operating temperature range matches the -40 °C to +125 °C specification provided in the product data sheet before finalizing procurement.

Selection Notes

Select this component when hex inversion with Schmitt-trigger action is required for noise immunity. Ensure the design accommodates the 1.65 V to 3.6 V supply voltage range. Verify that the DHVQFN14 package dimensions fit the PCB layout constraints and that thermal dissipation requirements are met within the specified ambient temperature limits.

Part Context

This part belongs to the 74ALVC14 family of hex inverters. The 'BQ' suffix indicates the DHVQFN14 leadless package variant, while '115' denotes the standard reel packaging format. It is distinct from other 74-series logic families due to its ALVC speed and low-voltage capabilities combined with Schmitt-trigger input characteristics.

Replacement Considerations

Check for other 74ALVC14 variants with different package options such as SO14 or TSSOP14 if pin compatibility allows. Verify functional equivalence regarding propagation delay and supply voltage ranges before substituting.
