Nexperia USA Inc. 74LVC1GU04GX,125

Overview

74LVC1GU04GX,125 from Nexperia is a single unbuffered CMOS inverter optimized for level-shifting and signal conditioning in mixed-voltage systems. It operates across 1.65 V to 5.5 V supply, accepts 5.5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and is rated for -40 °C to +125 °C. It serves as a logic-level translator in low-power sensor interface circuits.

For engineers reviewing the 74LVC1GU04GX,125 datasheet, 74LVC1GU04GX,125 pinout, 74LVC1GU04GX,125 application, or 74LVC1GU04GX,125 equivalent, key selection criteria include input overvoltage tolerance, propagation delay down to 0.5 ns at 5 V, thermal-enhanced X2SON5 package (SOT1226-3), and guaranteed operation across automotive-grade temperature range.

Technical Context

This device implements a single-stage unbuffered inverter topology with no internal gain staging-enabling minimal propagation delay and high noise immunity. Its input stage is designed for overvoltage tolerance up to 5.5 V independent of VCC, allowing direct interfacing with 5 V logic while powered from 1.65–3.3 V rails.

The output stage provides symmetrical sourcing/sinking capability (±24 mA at VCC = 3.0 V) and supports dynamic loading up to 50 pF. Propagation delay varies with supply voltage: 0.5 ns (min) to 4.0 ns (max) over 4.5–5.5 V, with measurement reference at 0.5 × VCC for input/output thresholds.

FAQ

Can 74LVC1GU04GX,125 be used as a linear amplifier?

Yes-per Nexperia Application Note AN10775, this unbuffered inverter can operate in its linear region when biased with appropriate feedback resistors (e.g., R1 ≥ 3 kΩ, R2 ≤ 1 MΩ). Typical unity-gain bandwidth is 5 MHz, and output swing is centered at 0.5 × VCC with peak-to-peak amplitude of VCC − 1.5 V. Biasing must avoid saturation to maintain linearity.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies dynamic characteristics up to 50 pF load capacitance with defined timing (tPLH/tPHL) and output voltage swing (VOL/VOH). Driving >50 pF may increase propagation delay beyond spec and degrade edge rates; for loads exceeding 50 pF, add a series resistor (e.g., 22 Ω) near the output to damp ringing and maintain signal integrity.

Does the n.c. pin on SOT1226-3 require PCB connection or keep-out?

Pin 1 is designated "n.c." (no connect) and is not internally bonded. Per Nexperia's package drawing SOT1226-3, it must remain unconnected-neither soldered nor routed. PCB layout must exclude copper pads or traces beneath this terminal to prevent unintended coupling or mechanical stress on the die attach.

How does thermal performance of SOT1226-3 compare to SOT753 for continuous operation at +125 °C?

SOT1226-3 (X2SON5) has a thermal derating slope of 3.0 mW/K above 67 °C, versus 3.8 mW/K above 85 °C for SOT753 (SC-74A). At +125 °C ambient, SOT1226-3 maintains ~20 % higher usable power dissipation (Ptot ≈ 180 mW vs. ~150 mW), making it preferable for thermally dense layouts where junction temperature margin is critical.
