Overview
The SN74AHC14QDRQ1 is an automotive-grade hex Schmitt-trigger inverter from Texas Instruments, part of the SN74AHC14-Q1 series. It operates within a supply voltage range of 2 V to 5.5 V and supports a maximum clock frequency of 66 MHz at 5 V. The device features push-pull outputs with low-level and high-level output currents of 8 mA each. It is housed in a 14-pin SOIC package and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Hex Schmitt-trigger configuration for noise immunity
- Automotive qualification under AEC-Q100 standards
- Wide supply voltage operation from 2 V to 5.5 V
- Push-pull output structure for robust driving capability
Applications
- Signal conditioning in noisy automotive environments
- Waveform shaping for digital systems
- Oscillator circuits requiring hysteresis
- Level shifting between different voltage domains
Procurement Notes
Verify the specific suffix 'QDRQ1' against the official Texas Instruments datasheet to confirm the SOIC-14 package and automotive grade designation. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the manufacturer's part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status as per the latest product information data sheet.
Selection Notes
Select this component when Schmitt-trigger action is required to clean up slow-rising or noisy input signals in automotive applications. The AHC logic family offers lower power consumption compared to standard HC devices while maintaining similar speed. Consider the 14-pin SOIC package constraints and the -40°C to +125°C temperature range suitability for your specific environmental conditions.
Part Context
This device belongs to the SN74AHC14-Q1 family of automotive hex inverters. It shares functional similarities with other AHC series logic gates but is specifically optimized for automotive reliability and noise tolerance. The Q1 suffix denotes automotive qualification, distinguishing it from commercial variants like the SN74AHC14DR.
