Nexperia USA Inc. 74LVC1G14GX4Z

Overview

74LVC1G14GX4Z from Nexperia is a single Schmitt-trigger inverter in X2SON4 package (SOT1269-2), operating from 1.65 V to 5.5 V supply, with overvoltage-tolerant 5.5 V inputs, ±24 mA output drive at 3.0 V, IOFF-enabled partial power-down protection, and hysteresis of 0.31 V (typ) at 3.0 V - used for noise-immune signal conditioning in mixed-voltage sensor interfaces.

For engineers reviewing the 74LVC1G14GX4Z datasheet, 74LVC1G14GX4Z pinout, 74LVC1G14GX4Z application, or 74LVC1G14GX4Z equivalent, this page delivers verified package mapping (X2SON4, 4-terminal), confirmed Schmitt-trigger transfer characteristics (VT+ = 1.29 V / VT− = 0.88 V at VCC = 3.0 V), IOFF behavior under VCC = 0 V, and real-world use in relaxation oscillators and pulse shaping circuits.

Technical Context

This device implements a CMOS-based Schmitt-trigger inverter with asymmetric input thresholds enabling robust noise rejection on slow-rising signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs remain biased up to 5.5 V.

It supports translation between 3.3 V and 5 V logic domains without level shifters, thanks to overvoltage-tolerant inputs and rail-to-rail output swing. Propagation delay is 0.7 ns (min) to 7.0 ns (max) across 1.65–3.6 V supply range, with CPD = 15.4 pF at 3.3 V defining dynamic power consumption.

FAQ

What is the maximum input voltage the 74LVC1G14GX4Z can tolerate when VCC = 1.8 V?

The device tolerates input voltages up to 5.5 V regardless of VCC level, per datasheet Table 5 (VI input voltage limit). This overvoltage capability allows safe interfacing with 5 V sensors or microcontrollers even when powered from 1.8 V, eliminating external clamping diodes or level shifters.

Does the 74LVC1G14GX4Z support true bidirectional I/O or bus-hold functionality?

No - it is a unidirectional inverter only, with dedicated input (A) and output (Y) pins. It does not include bus-hold, weak pull-up/down, or direction control. The IOFF feature disables output drive during power-down but does not enable reverse signal flow.

Can the 74LVC1G14GX4Z be used to build a precision oscillator with stable frequency?

It supports RC-based relaxation oscillators (per Fig. 10), but frequency stability depends entirely on external R/C tolerance and temperature drift. No internal compensation or trimming is provided; for ppm-level accuracy, a quartz crystal oscillator or dedicated timer IC is required.

Is the X2SON4 package of 74LVC1G14GX4Z compatible with standard reflow profiles for lead-free soldering?

Yes - the SOT1269-2 package is qualified for JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and supports standard Pb-free reflow profiles (peak 260 °C, 10–30 sec above 217 °C), as confirmed in Nexperia's package reliability documentation.
