74AHCT1G14DBVRG4

Overview

The SN74AHCT1G14DBVRG4 is a single Schmitt-trigger inverter gate from Texas Instruments, part of the 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum propagation delay of 8 ns at 5 V with a 50 pF load. The device provides high-level and low-level output currents of 8 mA each, with a maximum static current of 1 µA. It supports input logic levels compatible with CMOS standards (0.5 V to 0.6 V for low, 2 V for high) and functions reliably across an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Integrates Schmitt-trigger action to filter noisy signals and ensure clean transitions.
• Provides robust drive capability with 8 mA output current sourcing and sinking.
• Ensures compatibility with standard CMOS logic families through AHCT input thresholds.

Applications

• Signal conditioning for noisy digital environments
• Pulse width modulation signal shaping
• Oscillator circuit timing references

Procurement Notes

Verify the complete ordering suffix 'G4' to confirm RoHS compliance and green manufacturing status. Ensure the package designation matches the required SOT-23-5 footprint. Confirm that the specific revision level aligns with your design's documentation requirements before finalizing procurement orders.

Selection Notes

Select this component when CMOS logic compatibility is required alongside noise immunity provided by Schmitt triggers. It serves as a direct replacement for standard inverters where signal integrity is critical. Consider the 8 mA drive strength for moderate capacitive loads within the specified voltage and temperature ranges.

Part Context

This device belongs to the 74AHCT1G14 series of single-function gates. It shares the same logical function and pinout as the non-green variant SN74AHCT1G14DBVR, differing primarily in environmental compliance attributes. The G4 suffix indicates adherence to specific lead-free manufacturing processes defined by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers include SN74AHCT1G14DBVR and SN74AHCT1G14DBVRE4. These alternatives maintain identical electrical characteristics and physical dimensions while varying only in packaging or compliance specifications.
