SN74AC14DRG4

Overview

The SN74AC14DRG4 is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports a maximum load capacitance of 50 pF. The device features six independent inverting channels with Schmitt-trigger inputs for noise filtering. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 3.90 mm. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates six independent inverting logic channels within a single integrated circuit package.
• Incorporates Schmitt-trigger input stages to provide defined threshold voltages and hysteresis for effective noise rejection.
• Supports operation across a wide power supply voltage range from 2 volts to 6 volts.

Applications

• Signal conditioning for noisy digital environments requiring noise immunity
• Waveform shaping of slow-rise or slow-fall time signals
• Pulse generation circuits utilizing the hysteresis characteristics

Procurement Notes

Verify the specific ordering suffix DRG4 to confirm the tape-and-reel packaging format and lead-free composition. Ensure compatibility with standard SOIC-14 footprints during PCB layout. Confirm RoHS compliance status matches current regulatory requirements for the target market. Validate that the AC logic family specifications align with the system's voltage and speed requirements.

Selection Notes

Select this component when high noise immunity is required for digital signal inversion. The Schmitt-trigger feature distinguishes it from standard inverters, making it suitable for interfaces with analog-like waveforms. Consider the AC series performance characteristics relative to other logic families if lower power consumption or different voltage ranges are prioritized over the specific switching speeds provided here.

Part Context

This part belongs to the SN74AC series of advanced CMOS logic devices produced by Texas Instruments. The 'A' denotes the Advanced CMOS technology, while 'C' indicates the inclusion of Schmitt-trigger inputs. The suffix 'G4' specifies the green, lead-free, and RoHS-compliant manufacturing variant. It serves as a functional equivalent to other hex Schmitt-trigger inverters in the broader 74xx logic ecosystem.

Replacement Considerations

The SN74AC14DR is a direct manufacturer-recommended alternative offering identical electrical characteristics without the G4 suffix. Other compatible options include the SN74ACT14DRG4 for faster switching speeds and the SN74HC14 variants for different drive capabilities. Verify pinout compatibility before substituting with non-TI equivalents.
