Nexperia USA Inc. 74LVC1G14GX,125

Overview

74LVC1G14GX from Nexperia is a single Schmitt-trigger inverter IC designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, features ±24 mA output drive at 3.0 V, IOFF-enabled partial power-down protection, and supports -40 °C to +125 °C operation in the X2SON5 (SOT1226-3) package. It is used in wave shaping, relaxation oscillators, and level translation between 3.3 V and 5 V logic domains.

For engineers reviewing the 74LVC1G14GX datasheet, 74LVC1G14GX pinout, 74LVC1G14GX application, or 74LVC1G14GX equivalent, this page delivers verified electrical parameters, thermal-enhanced X2SON5 package details, Schmitt-trigger hysteresis values (e.g., VH = 0.64 V typ at VCC = 3.0 V), IOFF leakage specs (<±2 μA), and real-world use cases including monostable multivibrator design and noise-immune clock edge regeneration.

Technical Context

The 74LVC1G14GX implements a CMOS-based Schmitt-trigger inverter with asymmetric input thresholds (VT+ = 1.71 V max, VT− = 1.24 V min at VCC = 3.0 V), enabling robust noise rejection on slow-rising signals. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), and supports unlimited input rise/fall times without increased dynamic power-critical for RC-based timing circuits and low-frequency sensor interfacing.

FAQ

What is the maximum input voltage the 74LVC1G14GX can tolerate when VCC = 1.8 V?

The 74LVC1G14GX accepts input voltages up to 5.5 V regardless of VCC level, per datasheet Table 5 (VI input voltage limit). This overvoltage tolerance allows safe interfacing of 5 V signals into 1.8 V systems without external clamping or level-shifting circuitry.

Does the 74LVC1G14GX support true bidirectional level translation?

No-the 74LVC1G14GX is a unidirectional inverter with Schmitt-trigger input and CMOS output. It translates high-to-low voltage levels (e.g., 5 V → 3.3 V) but does not support reverse-direction translation or bus arbitration. Bidirectional operation requires dedicated translators like TXB0104.

How does the IOFF feature behave during power sequencing?

When VCC drops to 0 V, the IOFF circuit automatically disables the Y output, limiting leakage current to <±2 μA (Table 7). This prevents back-current flow from powered downstream logic into the unpowered device-critical for safe hot-plug and multi-rail power-up sequences.

Can the 74LVC1G14GX be used in a crystal-less oscillator configuration?

Yes-it is commonly used in relaxation oscillators (Fig. 10) with external R and C components to generate stable low-frequency clocks (1–100 kHz). The Schmitt-trigger hysteresis ensures predictable threshold crossing, eliminating need for external comparators or crystals in non-precision timing applications.
