SN74AHC14DG4

Overview

The SN74AHC14DG4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the AHC logic series and utilizes CMOS technology. The device operates within a supply voltage range of 2 V to 5.5 V. It features six independent inverters, each equipped with Schmitt-trigger inputs for noise filtering. The component supports output currents of 8 mA at both high and low states. It is housed in a 14-pin SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides robust noise filtering through defined input thresholds
• Supports wide supply voltage operation from 2 V to 5.5 V
• Delivers symmetrical 8 mA drive capability for standard loads

Applications

• Signal wave shaping and conversion
• Noise elimination in digital circuits
• Pulse generation applications

Procurement Notes

Verify the specific suffix DG4 against official Texas Instruments documentation to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the exact package type and temperature grade required for the design. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential product changes or notices affecting this specific variant.

Selection Notes

Select this component when six isolated inverting channels with hysteresis are required. The AHC series offers speed and power characteristics superior to standard 74HC devices. Verify that the 14-pin SOIC footprint aligns with the PCB layout constraints. Confirm that the 2 V to 5.5 V supply range covers the system's operational voltage requirements.

Part Context

This part is a member of the SN74AHC14 family, which includes variants with different packages such as PW (TSSOP) and DR (SOIC). The DG4 designation specifically identifies the SOIC-14 package configuration. It serves as a functional equivalent to other hex Schmitt-trigger inverters within the broader 74-series logic ecosystem, providing standardized interface capabilities for digital systems.

Replacement Considerations

Direct substitutes include SN74AHC14DR and SN74AHC14PW. Verify pinout compatibility and electrical specifications before substitution.
