Automotive-grade hex inverter with Schmitt-trigger inputs
The SN74LVC14AQDRQ1 is a Texas Instruments hex inverter from the Automotive, AEC-Q100 74LVC series, integrating six independent Schmitt-trigger inverters in a single 14-SOIC package. The Schmitt-trigger inputs provide hysteresis on the rising and falling edges, rejecting noise on slow or noisy input signals — critical for automotive power rails and sensor interfaces where ground bounce or ripple would otherwise cause false toggling. The 10 µA max quiescent current keeps standby draw negligible in always-powered ECU modules.
Timing and drive — what the numbers mean for the board
Maximum propagation delay is 6.4 ns at 3.3V with a 50 pF load. At a 50 MHz bus rate (20 ns period), this leaves 13.6 ns of timing margin per stage — enough for a clean signal path through two or three inverters in series before setup-time violations appear at the receiving flip-flop. Symmetric 24 mA output drive (source and sink) at 3.3V means the part can drive up to five standard 74LVC loads per output without exceeding the fan-out limit, or switch a small LED with a series resistor. Input logic thresholds are specified as 0.4V to 0.8V for low and 2V minimum for high at 3.3V supply — the hysteresis window is approximately 1.2V, which rejects 1Vpp noise on a 3.3V rail.
