Nexperia USA Inc. 74HCT2G14GW-Q100H

Overview

74HCT2G14GW-Q100 from Nexperia is a dual inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5 V to 5.5 V supply range, and hysteresis of 0.4 V to 0.71 V at VCC = 4.5–5.5 V. It transforms slow/noisy input edges into clean digital outputs in engine control units and body electronics.

For engineers reviewing the 74HCT2G14GW-Q100 datasheet, 74HCT2G14GW-Q100 pinout, 74HCT2G14GW-Q100 application, or 74HCT2G14GW-Q100 equivalent, key selection criteria include TTL-level input compatibility, guaranteed operation up to +125 °C, Schmitt-trigger hysteresis (VT+ = 1.20–1.90 V, VT− = 0.50–1.20 V), propagation delay ≤48 ns at 4.5 V/50 pF, and TSSOP6 (SOT363-2) package with 1.25 mm body width.

Technical Context

This device implements two independent CMOS inverting Schmitt triggers with input clamp diodes enabling robust interfacing to overvoltage signals via current-limiting resistors. Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V) ensure direct compatibility with legacy 5 V logic families.

The Schmitt architecture provides noise immunity by enforcing distinct positive-going (VT+) and negative-going (VT−) switching thresholds, delivering jitter-free output transitions even with slowly varying or noisy inputs-critical for signal conditioning in automotive sensor interfaces and oscillator circuits.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per AEC-Q100 qualification. Operation above 5.5 V voids automotive qualification and risks exceeding junction temperature limits under load, especially at +125 °C ambient.

Can this device interface directly with a 12 V sensor output?

Yes-input clamp diodes allow safe interfacing to voltages exceeding VCC when used with an external current-limiting resistor. For a 12 V sensor, a 10 kΩ resistor limits input current to <1 mA, staying well within the ±20 mA clamp rating and avoiding damage or logic upset.

Is the 74HCT2G14GW-Q100 pin-compatible with the 74HC2G14GW-Q100?

Yes-both share identical SOT363-2 (TSSOP6) pinout and footprint. However, the 74HC variant uses CMOS input thresholds (VIH ≈ 0.7×VCC), making it incompatible with TTL sources unless VCC ≥ 4.5 V and noise margins are verified; the HCT version guarantees TTL compatibility across its full 4.5–5.5 V range.

Does this part support hot-swap or live-insertion in automotive modules?

No-this device lacks Ioff (power-off protection) or IOZ (high-impedance on power-down) features. Applying input signals while VCC is absent or ramping may cause excessive supply current or undefined outputs; external isolation circuitry is required for hot-swap scenarios.
