SN74HC14QDRG4Q1

Inverter Gates Overview

The SN74HC14QDRG4Q1 is an automotive-grade hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the SN74HC14 series and utilizes CMOS logic technology. The device features six independent inverters with Schmitt-trigger inputs, packaged in a 14-pin SOIC (SOIC-14) surface-mount format. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +125°C. The component holds AEC-Q100 qualification for automotive applications. Key electrical parameters include a propagation delay of 21 ns, a high-level output current of -4 mA, and a low-level output current of 4 mA.

Inverter Gates Feature Summary

• Incorporates six independent Schmitt-trigger inverters to provide noise filtering and waveform shaping capabilities.
• Designed for automotive environments with AEC-Q100 qualification ensuring reliability under harsh conditions.
• Supports extended industrial temperature operation ranging from -40°C to +125°C.

Inverter Gates Applications

• Automotive signal conditioning circuits requiring noise immunity

Inverter Gates Procurement Notes

Verify the complete part number including the suffix G4, which indicates lead-free and RoHS-compliant manufacturing. Confirm the package type is SOIC-14 and that the device carries AEC-Q100 automotive qualification. Ensure the order specifies the correct tape-and-reel quantity if applicable. Cross-reference the manufacturer's datasheet for specific handling and storage requirements related to moisture sensitivity levels.

Inverter Gates Selection Notes

Select this component when designing automotive systems requiring robust noise rejection for digital signals. The Schmitt-trigger input characteristic makes it suitable for slow-rising or noisy waveforms. Consider the 2 V to 6 V supply range compatibility with standard automotive power rails. Verify that the SOIC-14 package fits the PCB layout constraints and thermal management requirements of the target application.

Inverter Gates Part Context

This device is part of the broader SN74HC14 family of hex Schmitt-trigger inverters. The QDRG4 suffix denotes the automotive grade, lead-free composition, and specific packaging configuration. It shares functional similarities with other HC-series logic but is distinguished by its automotive qualification and extended temperature rating compared to commercial variants.

Inverter Gates Replacement Considerations

Direct replacements must maintain the hex Schmitt-trigger inverter function, SOIC-14 package, and AEC-Q100 automotive qualification. Verify pinout compatibility and electrical specifications such as supply voltage range and output drive current before substitution.
