Nexperia USA Inc. 74LVC2GU04GW,125

Overview

74LVC2GU04GW,125 from Nexperia is a dual unbuffered CMOS inverter IC operating from 1.65 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V and ±24 mA output drive at 3.0 V. It enables level translation between 3.3 V and 5 V logic domains and supports industrial temperature operation from –40 °C to +125 °C in TSSOP6 (SOT363-2) package.

For engineers reviewing the 74LVC2GU04GW,125 datasheet, 74LVC2GU04GW,125 pinout, 74LVC2GU04GW,125 application, or 74LVC2GU04GW,125 equivalent, key selection criteria include input voltage tolerance, propagation delay consistency across 1.65–5.5 V supply range, dual-gate unbuffered architecture for oscillator and linear amplifier use, and thermal derating behavior in TSSOP6 packaging.

Technical Context

This device implements two independent unbuffered inverters-each with no internal buffering stage-enabling direct feedback configurations essential for crystal oscillators and linear amplifiers. Its rail-to-rail input tolerance and symmetrical output drive support bidirectional voltage translation without external biasing.

The unbuffered topology yields low propagation delay (as low as 0.3 ns at 5 V) and enables stable oscillation when combined with external crystal and load capacitors. Input hysteresis is not present; logic thresholds are defined by standard CMOS ratios (VIH = 0.75×VCC, VIL = 0.25×VCC), ensuring predictable switching in mixed-voltage systems.

FAQ

Can the 74LVC2GU04GW,125 be used as a linear amplifier?

Yes-when DC-biased via external resistors (R1 ≥ 3 kΩ, R2 ≤ 1 MΩ), it operates in its linear region with typical open-loop gain of 20 and 5 MHz unity-gain bandwidth. Output swing is centered at 0.5×VCC with peak-to-peak amplitude of VCC − 1.5 V, enabling low-component-count analog signal conditioning.

What is the maximum clock frequency achievable in a Pierce oscillator using this device?

While not specified as a clock generator, application note Fig. 9 demonstrates stable oscillation up to 20 MHz using 47 pF and 22 pF load capacitors. Performance depends on crystal ESR and external resistor values; typical startup time is <100 μs at 25 °C with 3.3 V supply.

Does the 74LVC2GU04GW,125 support hot-swap or live-insertion?

No-its absolute maximum input voltage is 5.5 V and supply must be established before applying input signals. Simultaneous application of input voltage and VCC can cause latch-up. Use power sequencing control or series current-limiting resistors if hot-swap operation is required.

How does the TSSOP6 (SOT363-2) package compare thermally to XSON6 variants?

The GW package has a junction-to-ambient thermal resistance (RθJA) of 290 K/W, lower than SOT886 (320 K/W) and SOT1115 (340 K/W). At 24 mA output current and 125 °C ambient, junction temperature rise is ~17 °C lower than SOT1115-critical for sustained oscillator or amplifier operation.
