AEC-Q100 qualified hex Schmitt-trigger inverter for automotive signal conditioning
The Texas Instruments SN74HC14QDRQ1 is a hex inverter with Schmitt-trigger inputs, part of the Automotive, AEC-Q100, 74HC logic family. It integrates six independent inverter channels, each with a single input, in a 14-SOIC surface-mount package. The Schmitt-trigger action provides clean switching on noisy or slowly changing input signals, making it a standard choice for debouncing switch contacts, squaring up oscillator waveforms, and conditioning sensor outputs in automotive ECUs, body-control modules, and industrial controllers operating from 2 V to 6 V supplies.
21 ns propagation delay — timing budget for the bus
For automotive programs that run several years, this avoids the supply-chain disruption of an unplanned obsolescence event.
The AEC-Q100 qualification adds the reliability screening (temperature cycling, HAST, early-life failure rate) that automotive tier-1s and industrial OEMs require for zero-defect programs.
The active lifecycle means standard lead times apply through the factory channel, and the ROHS3 compliance avoids any restriction on EU-market shipments.
