Nexperia USA Inc. 74HC1G14GV,125

Overview

74HC1G14GV,125 from Nexperia is a single-channel CMOS inverting Schmitt trigger logic gate in SC-74A (SOT753) package, operating from 2.0 V to 6.0 V supply, with ±12.5 mA output drive, 26 ns max propagation delay at 6.0 V/50 pF, and -40 °C to +125 °C temperature range - used for noise-immune signal conditioning in sensor interface and oscillator circuits.

For engineers reviewing the 74HC1G14GV,125 datasheet, 74HC1G14GV,125 pinout, 74HC1G14GV,125 application, or 74HC1G14GV,125 equivalent, this page delivers verified pin functions, Schmitt-trigger hysteresis values (0.6–1.6 V), input threshold voltages (VT+ = 2.1–4.2 V at VCC = 6.0 V), static/dynamic electrical specs, and real-world use cases in waveform shaping and relaxation oscillators.

Technical Context

This device implements a single inverter with hysteresis via internal positive feedback, enabling clean digital transitions from slow-rising analog inputs. Its Schmitt-trigger input accepts unlimited input rise/fall times and features clamp diodes for overvoltage tolerance when used with current-limiting resistors.

It operates across two logic families: 74HC1G14GV uses CMOS-level inputs (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), while 74HCT1G14GV supports TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max). Both versions deliver symmetrical output impedance and balanced tPLH/tPHL delays.

FAQ

What is the maximum recommended operating frequency for 74HC1G14GV,125 in oscillator applications?

The device supports reliable relaxation oscillator operation up to ~1 MHz depending on external R-C values and supply voltage. At VCC = 6.0 V, typical propagation delay is 11–26 ns, limiting practical free-running frequency to <10 MHz; however, oscillator stability and jitter performance are optimal below 1 MHz due to hysteresis-dependent timing precision and load capacitance effects.

Can 74HC1G14GV,125 be used with 3.3 V microcontrollers without level shifting?

Yes - its CMOS input thresholds scale with VCC (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), so at 3.3 V supply, VIH ≈ 2.3 V and VIL ≈ 1.0 V, fully compatible with standard 3.3 V GPIO outputs. No level shifter is needed when both controller and 74HC1G14GV,125 share the same 3.3 V rail.

Why does Pin 1 show "n.c." and how should it be handled on the PCB?

Pin 1 is not internally connected - it serves only as a mechanical alignment marker and carries no electrical function. It must remain unconnected (floating) on the PCB; neither routing nor grounding is permitted, as doing so may compromise package integrity or thermal performance in the SC-74A footprint.

How does the Schmitt trigger hysteresis improve noise immunity compared to a standard inverter?

Hysteresis creates two distinct input thresholds: VT+ for rising edges and VT− for falling edges. This 0.6–1.6 V separation prevents output oscillation when input signals hover near a single threshold due to noise - unlike standard inverters, which would chatter repeatedly on noisy edges, causing false interrupts or timing errors in downstream logic.
