Nexperia USA Inc. 74HC3G14DC,125

Overview

74HC3G14DC,125 from Nexperia is a triple inverting Schmitt trigger IC in VSSOP8 package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, ±25 mA output drive, and hysteresis of 0.8–1.7 V (VCC = 2.0–6.0 V). It conditions slow/noisy input edges into clean digital outputs for timing and waveform shaping in industrial control interfaces.

For engineers reviewing the 74HC3G14DC,125 datasheet, 74HC3G14DC,125 pinout, 74HC3G14DC,125 application, or 74HC3G14DC,125 equivalent, key selection criteria include Schmitt-trigger hysteresis width, propagation delay (13–125 ns), input threshold symmetry, VSSOP8 thermal derating (4.9 mW/K above 99 °C), and -40 °C to +125 °C extended temperature operation.

Technical Context

This device implements three independent inverting Schmitt triggers with clamped inputs enabling overvoltage-tolerant interfacing via current-limiting resistors. Each channel features asymmetric thresholds (VT+ = 1.00–4.20 V, VT- = 0.30–2.60 V) and hysteresis (VH = 0.30–1.70 V), ensuring noise immunity against slow-rising signals.

Its dynamic behavior is defined by propagation delays (tpd = 13–125 ns) and transition times (tt = 5–75 ns), both strongly dependent on VCC and load; power dissipation is governed by CPD = 10 pF and supply current ICC ≤ 1.0 μA (static) or up to 50 mA (absolute max).

FAQ

What is the maximum recommended operating frequency for 74HC3G14DC,125?

The device does not specify a maximum clock frequency, but its propagation delay (13–125 ns) and transition time (5–75 ns) limit practical use to ~10 MHz in typical RC oscillator or waveform-shaping configurations. At VCC = 6.0 V and 25 °C, tpd = 13 ns (typ) supports reliable operation up to 30 MHz in low-capacitance, well-decoupled layouts.

Can 74HC3G14DC,125 safely interface with 12 V sensor signals?

Yes-its integrated input clamp diodes allow direct connection to voltages up to VCC + 0.5 V. To interface with 12 V signals, use a series current-limiting resistor (e.g., 10 kΩ with VCC = 5 V) to restrict IIK to ≤±20 mA, per absolute maximum ratings. No external diodes are required.

How does temperature affect hysteresis width in 74HC3G14DC,125?

Hysteresis voltage (VH = VT+ − VT−) remains stable across temperature: at VCC = 4.5 V, VH = 0.60–1.40 V (-40 °C to +125 °C), with minimal drift. Data sheet Table 8 confirms VH min/max values are specified across all three temperature ranges, confirming design suitability for thermally varying environments.

Is 74HC3G14DC,125 pin-compatible with 74HCT3G14DC,125?

Yes-both share identical VSSOP8 (SOT765-1) pinout and mechanical footprint. However, 74HCT3G14DC,125 uses TTL-compatible inputs (VIH ≈ 2.0 V), while 74HC3G14DC,125 requires CMOS-level inputs (VIH ≈ 0.7×VCC). Electrical substitution requires verifying source logic family compatibility.
