Nexperia USA Inc. 74HC1G14GV-Q100H

Overview

74HC1G14GV-Q100 from Nexperia is a single-channel CMOS inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0–6.0 V, 5-pin SC-74A (SOT753) package, and hysteresis voltage of 0.6–1.6 V at VCC = 6.0 V. It transforms slow-rising input signals into clean digital outputs in noise-prone vehicle subsystems.

For engineers reviewing the 74HC1G14GV-Q100 datasheet, 74HC1G14GV-Q100 pinout, 74HC1G14GV-Q100 application, or 74HC1G14GV-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis width, propagation delay under 32 ns at 6.0 V/50 pF, TTL/CMOS input compatibility, automotive temperature compliance, and SC-74A footprint compatibility with space-constrained ECUs.

Technical Context

This device implements a single inverter stage with asymmetric input threshold switching (VT+ and VT−) to provide noise-immune signal conditioning. Its Schmitt-trigger architecture enables reliable operation with slow input edges and high immunity to ground bounce or EMI in automotive wiring harnesses.

Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The output stage delivers symmetrical drive capability (±12.5 mA) and balanced propagation delays (tPLH ≈ tPHL), supporting stable relaxation oscillator configurations without external feedback compensation.

FAQ

What is the maximum recommended operating voltage for 74HC1G14GV-Q100?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per datasheet Table 6. Operation above 6.0 V risks accelerated parametric drift and violates JEDEC JESD7A compliance; sustained use beyond 6.0 V voids AEC-Q100 qualification guarantees.

Can 74HC1G14GV-Q100 drive a 10 mA LED directly?

Yes - its output can source or sink up to ±12.5 mA (Table 5), making it suitable for driving standard 2 mA–10 mA indicator LEDs. Use a series current-limiting resistor calculated as R = (VCC − VLED)/IOUT, and ensure total power dissipation (including P = I²R + CPD×VCC²×f) remains below 250 mW at max ambient temperature.

Does this part support true 3.3 V logic interfacing?

Yes - at VCC = 3.3 V, the 74HC1G14GV-Q100 maintains valid CMOS input thresholds (VT+ ≈ 2.2 V, VT− ≈ 1.1 V) and output swing (VOH > 3.1 V, VOL < 0.2 V), enabling interoperability with 3.3 V microcontrollers without level translation, provided VI stays within 0–VCC.

How does the Schmitt trigger improve noise immunity versus a standard inverter?

It provides hysteresis - distinct upper (VT+) and lower (VT−) switching thresholds - so input noise must exceed the hysteresis voltage (VH = VT+ − VT−) to cause unintended output toggling. At VCC = 5.0 V, VH ≈ 1.0 V, giving >1 V noise margin versus 0 V margin in standard inverters, suppressing EMI-induced glitches in automotive harnesses.
