74AHC14BQ,115

Overview

The Nexperia 74AHC14BQ,115 is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes DHVQFN14 (SOT762-1) packaging with dimensions of 2.5 mm x 3 mm x 0.85 mm. Propagation delay ranges from 1.0 ns to 16.0 ns depending on load capacitance and voltage. Static characteristics include an input leakage current maximum of 2.0 μA at -40 °C to +125 °C and a supply current maximum of 40 μA under the same conditions.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for high noise immunity
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• CMOS technology providing low power dissipation and balanced propagation delays

Applications

• Wave and pulse shapers

Selection Notes

Select this component when a hex inverter with Schmitt-trigger action is required for signal conditioning or waveform generation. The AHC logic family offers CMOS input levels suitable for systems operating between 2.0 V and 5.5 V. Ensure the application environment remains within the specified temperature range of -40 °C to +125 °C and that input voltages do not exceed the absolute maximum ratings defined in the datasheet.

Part Context

This part belongs to the Nexperia 74AHC14 and 74AHCT14 series of hex inverting Schmitt triggers. The 'BQ' designation specifically identifies the DHVQFN14 package variant (SOT762-1), which is a plastic dual-in-line compatible thermal enhanced very thin quad flat package. This series provides a compact solution for digital logic inversion with hysteresis in space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements within the same package include other variants of the 74AHC14 series such as the SO14 (74AHC14D) or TSSOP14 (74AHC14PW). Cross-family replacements like the 74AHCT14BQ,115 are available but require verification of TTL input level compatibility versus the CMOS levels of the AHC series.
