Nexperia USA Inc. 74HC2GU04GV,125

Overview

74HC2GU04GV,125 from Nexperia is a dual unbuffered CMOS inverter in SC-74 (SOT457) package with 6 pins, operating from 2.0 V to 6.0 V supply, delivering balanced propagation delays as low as 5 ns at 6.0 V/50 pF, and rated for -40 °C to +125 °C ambient temperature. It features input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors.

For engineers reviewing the 74HC2GU04GV,125 datasheet, 74HC2GU04GV,125 pinout, 74HC2GU04GV,125 application, or 74HC2GU04GV,125 equivalent, key selection criteria include unbuffered gate behavior for linear amplifier/crystal oscillator use, rail-to-rail input voltage tolerance with clamping, low ICC (≤20 µA at 6.0 V), and guaranteed operation across extended industrial temperature range.

Technical Context

This device implements two independent unbuffered inverters - each consisting of a single CMOS inverter stage without internal buffering - enabling direct use in analog applications like crystal oscillators and linear amplifiers. Its unbuffered architecture yields symmetrical input/output capacitance and enables stable negative feedback configurations.

The inputs incorporate integrated clamp diodes to GND and VCC, allowing safe overvoltage interface when used with external current-limiting resistors. Propagation delay and transition time are tightly matched between channels (tpd ≤15 ns max at 4.5 V/50 pF), supporting precise timing-critical signal inversion in compact logic subsystems.

FAQ

Can 74HC2GU04GV,125 be used as a linear amplifier?

Yes - its unbuffered architecture allows DC biasing into the linear region using external feedback resistors. The datasheet provides a verified circuit (Fig. 12) achieving ~20× open-loop gain, VO(p-p) = VCC − 1.5 V centered at 0.5 × VCC, and 5 MHz unity-gain bandwidth, making it suitable for low-frequency sensor signal conditioning.

What is the purpose of the input clamp diodes?

The integrated clamp diodes (anode to GND, cathode to VCC) protect inputs from voltages exceeding the supply rails by shunting excess current through external series resistors. This enables safe interfacing to 5 V signals on a 3.3 V system or transient overvoltages without external diodes - a key differentiator versus buffered inverters.

How does temperature affect propagation delay?

Propagation delay increases with temperature: at VCC = 4.5 V/50 pF, tpd is 12 ns max at -40 °C to +85 °C but rises to 18 ns max across -40 °C to +125 °C. This 6 ns degradation is fully characterized and guaranteed, supporting timing margin analysis in extended-temperature designs.

Is 74HC2GU04GV,125 pin-compatible with other 6-pin dual inverters?

Yes - it shares the SOT457 (SC-74) footprint and identical pinout (1A-GND-2A-2Y-VCC-1Y) with industry-standard dual unbuffered inverters including 74HC04 variants in same package. However, functional compatibility requires verification of unbuffered behavior, as buffered equivalents (e.g., 74HC2G04) exhibit different AC characteristics and lack linear-mode capability.
