SN74AHC1G14DBVRE4

Overview

The SN74AHC1G14DBVRE4 is a single-channel inverter from the Texas Instruments AHC logic family, housed in an SOT-23-5 surface-mount package. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. The device features Schmitt-trigger inputs for noise immunity and provides balanced push-pull outputs with a maximum high-level output current of -8 mA and a low-level output current of 8 mA. Static supply current is limited to a maximum of 1 µA.

Feature Summary

• Schmitt-trigger input configuration ensures clean signal transitions by rejecting noise near switching thresholds.
• Balanced push-pull output stage provides symmetric drive strength for both high and low logic states.
• Over-voltage tolerant inputs allow safe operation when interfacing with higher voltage logic systems.

Applications

• Signal conditioning for noisy digital environments requiring hysteresis
• Waveform shaping of slow-rise or slow-fall signals
• Single-gate inversion in space-constrained portable electronics

Procurement Notes

Verify the E4 suffix indicates lead-free manufacturing compliant with RoHS standards. Confirm the DBVR variant designation corresponds to the specific reel packaging format required for automated assembly processes. Ensure the component meets the specified industrial temperature grade for your application environment.

Selection Notes

Select this component when a single inverting gate with Schmitt-trigger characteristics is required in a minimal footprint. The AHC series offers faster propagation delays compared to standard HC logic while maintaining CMOS power efficiency. Verify that the 2 V to 5.5 V supply range aligns with the system's power rails.

Part Context

This part belongs to the SN74AHC1Gxx series of single-function logic gates designed for compact applications. The AHC technology combines the speed of advanced CMOS processes with low power consumption. The DBVR package variant utilizes the SOT-23-5 form factor, suitable for high-density PCB layouts where board space is limited.

Replacement Considerations

Publicly confirmed substitute part numbers include SN74AHC1G14DBVT and SN74AHC1G14DCKR. These alternatives share identical logical functions and pinouts but may differ in packaging style or tape-and-reel specifications. Always verify electrical parameters against the original datasheet before substitution.
