Nexperia USA Inc. 74LVC2G14GV,125

Overview

74LVC2G14GV,125 from Nexperia is a dual inverting Schmitt trigger IC with 5 V tolerant inputs, designed for level translation between 3.3 V and 5 V logic domains. It features IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operates across 1.65 V–5.5 V supply range. Used in wave shaping and relaxation oscillator circuits in industrial control and sensor interface modules.

For engineers reviewing the 74LVC2G14GV,125 datasheet, 74LVC2G14GV,125 pinout, 74LVC2G14GV,125 application, or 74LVC2G14GV,125 equivalent, this device serves as a robust noise-immune signal conditioner in mixed-voltage digital systems requiring precise hysteresis thresholds and guaranteed power-down isolation.

Technical Context

The 74LVC2G14GV implements two independent CMOS inverters with Schmitt-trigger inputs, each exhibiting distinct positive-going (VT+) and negative-going (VT−) threshold voltages-e.g., VT+ = 1.30 V and VT− = 0.60 V at VCC = 3.0 V-yielding 0.70 V hysteresis. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down.

Input tolerance up to 5.5 V enables direct interfacing with legacy 5 V TTL sources while powered from 1.65–5.5 V supplies. Propagation delay is 3.9 ns typical (VCC = 3.3 V), and dynamic power dissipation is governed by CPD = 18.1 pF, supporting low-energy operation in battery-sensitive applications.

FAQ

Can 74LVC2G14GV,125 be used with a 1.65 V supply and 5 V input signals?

Yes. The device is fully specified for 1.65 V–5.5 V VCC and supports input voltages up to 5.5 V regardless of supply level. This enables safe 5 V signal reception while operating from 1.65 V, making it ideal for ultra-low-power sensor nodes interfacing with legacy 5 V peripherals.

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

IOFF disables the output buffers when VCC = 0 V, forcing them into high-impedance state. Measured IOFF leakage is ≤±2 μA, preventing damaging backflow current from live 5 V buses into a powered-down subsystem - essential for hot-plug and modular power architecture designs.

How does the Schmitt-trigger hysteresis improve performance over a standard inverter?

Hysteresis provides separate VT+ (1.30 V) and VT− (0.60 V) thresholds at 3.0 V supply, creating a 0.70 V noise margin. This prevents multiple toggling on slow or noisy edges - critical for debouncing mechanical switches, cleaning PWM ripple, or stabilizing analog comparator outputs driving digital logic.

Is the 74LVC2G14GV,125 pin-compatible with other dual Schmitt inverters in SC-74 packages?

Yes - it shares identical SOT457 (SC-74/TSOP6) pinout with industry-standard dual Schmitt inverters like SN74LVC2G14DBVR and 74AUP2G14GW. Pin 1 (1A), Pin 2 (GND), Pin 3 (2A), Pin 4 (2Y), Pin 5 (VCC), and Pin 6 (1Y) are functionally and physically aligned across these parts.
