Nexperia USA Inc. 74AHC3G04GD,125

Overview

74AHC3G04GD,125 from Nexperia is a triple CMOS inverter with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0 V–5.5 V supply range, featuring symmetrical output impedance, balanced propagation delays (typ. 3.1 ns at 5 V, CL = 15 pF), and specified for -40 °C to +125 °C ambient operation. It serves as a level translator and signal inversion element in mixed-voltage digital subsystems such as I²C bus buffering, GPIO signal conditioning, and logic-level adaptation between 3.3 V and 5 V domains.

For engineers reviewing the 74AHC3G04GD,125 datasheet, 74AHC3G04GD,125 pinout, 74AHC3G04GD,125 application, or 74AHC3G04GD,125 equivalent, this device is selected for low-power, high-noise-immunity discrete logic functions requiring precise timing control, rail-to-rail input tolerance, and compact XSON8 packaging in space-constrained industrial control and portable electronics designs.

Technical Context

The 74AHC3G04GD,125 implements three independent CMOS inverter gates with TTL-compatible input thresholds only in AHCT variants - this AHC version uses CMOS switching levels (VIH ≥ 3.85 V at VCC = 5.5 V; VIL ≤ 1.65 V). Its overvoltage-tolerant inputs enable safe interfacing with 5 V signals even when powered at 3.3 V or 2.5 V.

Dynamic performance is characterized by matched tPLH/tPHL propagation delays (≤7.0 ns max at VCC = 5.5 V, CL = 15 pF), low power dissipation capacitance (CPD = 9 pF per buffer), and stable operation under fast edge rates (Δt/ΔV ≤20 ns/V at VCC = 5.0 V), supporting clean signal inversion in high-speed digital control paths.

FAQ

Is 74AHC3G04GD,125 pin-compatible with 74AHCT3G04GD,125?

No - while both share identical XSON8 pinout and terminal numbering, the 74AHCT variant uses TTL input thresholds (VIH = 2.0 V min at VCC = 4.5 V), whereas the AHC version requires CMOS thresholds (VIH = 3.85 V min at VCC = 5.5 V). Swapping them may cause incorrect logic interpretation in 3.3 V systems with marginal noise margins.

Can 74AHC3G04GD,125 drive a 50 pF capacitive load at 5 V supply?

Yes - at VCC = 5.5 V and CL = 50 pF, the device guarantees tPD ≤ 9.5 ns (max) with VOL ≤ 0.55 V and VOH ≥ 3.70 V across -40 °C to +125 °C. Measured typical delay is 4.5 ns, confirming reliable operation into 50 pF loads including PCB trace and gate capacitance.

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature is +150 °C, but the recommended operating ambient limit is +125 °C. With XSON8's RθJA ≈ 220 K/W and Ptot derating starting at +68 °C (3.1 mW/K), sustained power dissipation must remain below ~120 mW at +125 °C ambient to maintain TJ < 150 °C.

Does 74AHC3G04GD,125 require external pull-up resistors on inputs?

No - inputs are internally protected and do not require pull-ups for default HIGH/LOW states. However, floating inputs must be avoided: each unused inverter input should be tied to VCC or GND to prevent increased ICC, oscillation, or ESD susceptibility. Unused outputs may be left unconnected.
