Nexperia USA Inc. 74HC1G14GW,125

Overview

74HC1G14GW,125 from Nexperia is a single-channel CMOS inverting Schmitt trigger logic gate in TSSOP5 (SOT353-1) 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 guaranteed operation from –40 °C to +125 °C. It transforms slow-rising input signals-such as those from sensors or RC networks-into clean, jitter-free digital outputs for timing and waveform conditioning in industrial control interfaces.

For engineers reviewing the 74HC1G14GW,125 datasheet, 74HC1G14GW,125 pinout, 74HC1G14GW,125 application, or 74HC1G14GW,125 equivalent, this device is selected for noise-immune signal conditioning where hysteresis, rail-to-rail input tolerance, and low-power CMOS compatibility are required-especially in relaxation oscillators, pulse shaping, and monostable multivibrator circuits.

Technical Context

The 74HC1G14GW,125 implements a single inverter stage with Schmitt-trigger input thresholds (VT+ = 2.1–4.2 V, VT− = 1.2–2.6 V at VCC = 6.0 V), delivering 1.6 V typical hysteresis. Its input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

It features symmetrical output impedance, balanced tPLH/tPHL propagation delays (11–32 ns depending on VCC and load), and static input leakage <1.0 μA at 6.0 V. The device complies with JESD7A (2.0–6.0 V), JESD8C (2.7–3.6 V), and JEDEC ESD standards (HBM >2000 V, CDM >1000 V).

FAQ

Can 74HC1G14GW,125 operate reliably at 2.0 V supply?

Yes. The device is fully specified down to 2.0 V: propagation delay is 155 ns max (CL = 50 pF), VT+ = 1.9 V min, VT− = 0.3 V max, and output drive remains ±12.5 mA. All static and dynamic parameters meet datasheet limits across –40 °C to +125 °C at this voltage.

What is the maximum capacitive load it can drive while maintaining timing specs?

The 74HC1G14GW,125 maintains its 26 ns max propagation delay specification up to 50 pF total load capacitance (including PCB trace and probe capacitance). Beyond 50 pF, tpd increases linearly - e.g., ~38 ns at 100 pF with VCC = 6.0 V - but functionality remains intact.

Is pin 1 of the TSSOP5 package marked, and how is it identified?

Yes. Per Nexperia marking code HF for 74HC1G14GW, the pin 1 indicator is a small dot or notch located on the lower-left corner of the device body, directly below the marking code. This aligns with JEDEC-standard SOT353-1 package orientation.

Does it require external pull-up or pull-down resistors on the input?

No. The Schmitt-trigger input has no internal pull-up or pull-down; however, its clamp diodes and defined VIH/VIL thresholds mean external biasing is only needed if the source is high-impedance and floats. For most active drivers (e.g., MCU GPIO, op-amp outputs), no external resistors are required.
