Nexperia USA Inc. 74LVC3G14GF,115

Overview

74LVC3G14GF,115 from Nexperia is a triple inverting Schmitt trigger IC with 5 V tolerant inputs, designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V supply, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and supports industrial temperature range (−40 °C to +125 °C). It is used in wave shaping, relaxation oscillators, and noise-immune timing circuits.

For engineers reviewing the 74LVC3G14GF,115 datasheet, 74LVC3G14GF,115 pinout, 74LVC3G14GF,115 application, or 74LVC3G14GF,115 equivalent, key selection considerations include input hysteresis voltage (0.70–1.90 V), propagation delay (0.5–4.7 ns), 5 V tolerance on all I/O, IOFF-enabled backflow prevention during power-down, and XSON8 package compatibility with high-density PCB layouts.

Technical Context

This device integrates three independent inverting Schmitt triggers, each with asymmetric hysteresis (VT+ and VT−) enabling robust noise rejection on slow-rising/falling signals. Its IOFF circuit actively disables outputs when VCC = 0 V, eliminating destructive current flow in partial-power-down systems.

The logic function is strictly inverting (L → H, H → L), with input thresholds scaling linearly with VCC - e.g., VT+ = 2.91 V (typ) and VT− = 1.86 V (typ) at VCC = 5.5 V, yielding 1.02 V (typ) hysteresis. All inputs tolerate up to 6.5 V regardless of VCC, supporting direct interfacing with legacy 5 V TTL and CMOS logic.

FAQ

What is the maximum input voltage the 74LVC3G14GF,115 can safely withstand?

The absolute maximum input voltage is +6.5 V, and the device maintains full 5 V tolerance across its entire operating supply range (1.65 V to 5.5 V). This rating is verified per IEC 60134 limiting values and applies regardless of VCC state, enabling direct connection to 5 V buses without external clamping.

Does the 74LVC3G14GF,115 support partial power-down mode?

Yes - it features an active IOFF circuit that disables all outputs when VCC = 0 V, limiting backflow current to ±2 μA maximum. This behavior is specified over −40 °C to +125 °C and is integral to the device's design, not an optional feature.

How does hysteresis vary with supply voltage?

Both VT+ and VT− scale approximately linearly with VCC. For example, at VCC = 3.0 V, VT+ = 1.30–2.40 V and VT− = 0.60–1.70 V (min–max over temperature), yielding VH = 0.40–1.40 V. At VCC = 5.5 V, VT+ = 2.20–3.80 V and VT− = 1.20–2.50 V, giving VH = 0.70–1.90 V.

Which package variant corresponds to the 74LVC3G14GF,115 ordering code?

The suffix "GF" maps to the SOT1203 package - an XSON8 variant with 1.35 mm × 1.0 mm × 0.35 mm body size and 0.35 mm pitch. Pin 1 is located at the lower-left corner beneath the "VK" top-side marking, consistent with Nexperia's XSON8 orientation standard.
