Nexperia USA Inc. 74HC2G14GW,125

Overview

74HC2G14GW,125 from Nexperia is a dual inverting Schmitt trigger IC in TSSOP6 (SOT363-2) package, operating from 2.0 V to 6.0 V supply, featuring CMOS-level inputs, ±20 mA output drive, 13–125 ns propagation delay (VCC = 6.0 V to 2.0 V, CL = 50 pF), and hysteresis voltage up to 1.7 V - used for noise-immune signal conditioning in industrial sensor interfaces.

For engineers reviewing the 74HC2G14GW,125 datasheet, 74HC2G14GW,125 pinout, 74HC2G14GW,125 application, or 74HC2G14GW,125 equivalent, this page delivers verified pin functions, real-world Schmitt-trigger threshold behavior (VT+ = 3.0–4.2 V, VT− = 1.5–2.6 V at VCC = 6.0 V), dynamic timing under load, thermal derating rules, and direct substitution guidance with technical differentiation.

Technical Context

This device integrates two independent inverting Schmitt triggers with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. Its hysteresis (VH = 0.8–1.7 V) rejects noise on slow-rising signals while delivering sharp TTL/CMOS-compatible outputs.

It supports unlimited input rise/fall times and operates across −40 °C to +125 °C. Static current consumption is ≤20 μA at VCC = 6.0 V, and dynamic power dissipation is governed by CPD = 10 pF, enabling low-power waveform shaping without external timing components.

FAQ

Can 74HC2G14GW,125 operate reliably at 2.0 V supply?

Yes. The datasheet guarantees full functionality at VCC = 2.0 V, including VOH ≥ 1.9 V and VOL ≤ 0.1 V with 20 μA load, and propagation delay ≤125 ns (CL = 50 pF). Input thresholds scale linearly: VT+ = 1.0–1.5 V and VT− = 0.3–0.9 V, enabling robust operation with weak-signal sources like photodiodes or high-impedance sensors.

What is the maximum capacitive load this device can drive without timing degradation?

The device is characterized up to CL = 50 pF, where tpd remains within spec (e.g., 13 ns at VCC = 6.0 V). Driving >50 pF increases transition time (tt) and propagation delay nonlinearly - for 100 pF, tt rises ~2.3× and tpd ~1.8× per typical curves. Use a buffer stage or reduce trace capacitance if driving long PCB runs or multiple gate inputs.

Does this part support hot-swap or live-insertion scenarios?

It features latch-up immunity exceeding 100 mA per JESD78 Class II Level B, and absolute maximum ratings allow VCC = −0.5 V to +7.0 V and input voltages from −0.5 V to VCC + 0.5 V. However, no dedicated hot-swap control logic exists - use external current limiting and sequencing if inserting into powered backplanes.

How does hysteresis behave across temperature and supply voltage?

Hysteresis voltage (VH = VT+ − VT−) varies from 0.3 V (VCC = 2.0 V) to 1.7 V (VCC = 6.0 V) at 25 °C, and decreases ~15% at −40 °C and +125 °C extremes. This is inherent to CMOS threshold tracking - design critical timing margins using worst-case VH = 0.3 V (low VCC, cold) and 1.4 V (high VCC, hot) per datasheet Tables 12 and 13.
