Nexperia USA Inc. 74LVC2G14GW-Q100H

Overview

74LVC2G14GW-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 supply voltage range 1.65 V to 5.5 V. It features 5 V-tolerant inputs, ±24 mA output drive at 3.0 V, and IOFF circuitry enabling partial power-down mode. It serves as a level translator and waveform shaper in mixed-voltage automotive sensor interfaces and timing circuits.

For engineers reviewing the 74LVC2G14GW-Q100 datasheet, 74LVC2G14GW-Q100 pinout, 74LVC2G14GW-Q100 application, or 74LVC2G14GW-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.40–1.40 V), propagation delay (0.5–4.7 ns), IOFF-enabled isolation, automotive temperature compliance, and TSSOP6 package compatibility with space-constrained PCB layouts.

Technical Context

This device implements two independent CMOS inverting Schmitt triggers with asymmetric input thresholds (VT+ and VT−) and programmable hysteresis (VH). Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and multi-rail automotive subsystems.

Input tolerance up to 5.5 V enables direct interfacing with legacy 5 V logic while powered from 1.65–3.3 V rails, and its low ICC (≤4 μA) and CPD (18.1 pF) support ultra-low-power operation in always-on vehicle modules like body control units and door modules.

FAQ

Can 74LVC2G14GW-Q100 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device supports 5.5 V-tolerant inputs across its full 1.65–5.5 V supply range. At VCC = 1.65 V, VI can reach 5.5 V without damage or functional degradation, enabling direct interfacing with legacy 5 V microcontrollers or sensors while maintaining low-power operation.

What is the purpose of the IOFF feature, and how does it behave during power-down?

IOFF disables both outputs when VCC = 0 V, forcing them into high-impedance state. This prevents reverse current flow from live 5 V buses into unpowered sections of the system - a critical safety requirement in automotive domain controllers undergoing partial shutdown or wake-up sequencing.

How does the Schmitt trigger hysteresis vary with supply voltage?

Hysteresis (VH = VT+ − VT−) increases with VCC: 0.40 V typical at 3.0 V, 0.92 V at 4.5 V, and 1.02 V at 5.5 V. This scaling ensures consistent noise margin relative to rail voltage, maintaining reliable switching even as supply drifts across automotive battery conditions (e.g., cold-crank 6 V or load-dump 18 V transients).

Is the 74LVC2G14GW-Q100 pin-compatible with non-automotive versions like 74LVC2G14GW?

Yes - identical pinout, package (SOT363-2), and DC/AC electrical characteristics. The "-Q100" suffix denotes AEC-Q100 qualification, including extended temperature testing, enhanced reliability screening, and automotive-specific traceability; no design changes affect pin compatibility or schematic reuse.
