Nexperia USA Inc. 74AHC1G04GW,125

Overview

74AHC1G04GW,125 from Nexperia is a single CMOS inverter with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0 V–5.5 V supply, delivering 7.1 ns typical propagation delay at 3.3 V/15 pF, and specified for -40 °C to +125 °C. It serves as a level translator in mixed-voltage logic interfaces, such as interfacing 3.3 V microcontrollers to 5 V peripherals.

For engineers reviewing the 74AHC1G04GW,125 datasheet, 74AHC1G04GW,125 pinout, 74AHC1G04GW,125 application, or 74AHC1G04GW,125 equivalent, key selection criteria include input voltage tolerance, propagation delay vs. load capacitance, output drive strength at 3.3 V and 5 V, and thermal performance in TSSOP5 packaging for space-constrained PCBs.

Technical Context

This device implements a single unbuffered inverting gate using advanced AHC CMOS technology, supporting rail-to-rail input switching thresholds (VIH = 3.85 V, VIL = 1.65 V at VCC = 5.5 V) and symmetrical output impedance for balanced rise/fall times. Its overvoltage-tolerant inputs enable safe operation when driven by signals exceeding VCC - critical in voltage translation scenarios.

The logic function is strictly inverting (A → Y), with no internal feedback or hysteresis. Static characteristics are guaranteed across full industrial temperature range (-40 °C to +125 °C), and dynamic performance is characterized at CL = 15 pF and CL = 50 pF under defined input transition rates (≤20 ns/V).

FAQ

Is 74AHC1G04GW,125 pin-compatible with 74AHCT1G04GW,125?

Yes - both share identical TSSOP5 (SOT353-1) pinout: Pin 1 (n.c.), Pin 2 (A), Pin 3 (GND), Pin 4 (Y), Pin 5 (VCC). However, their input threshold specifications differ: 74AHC1G04 uses CMOS thresholds, while 74AHCT1G04 uses TTL thresholds. Swapping them may cause incorrect logic interpretation if input voltages fall between the two threshold windows.

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

At VCC = 3.3 V, the device maintains ≤7.1 ns typical propagation delay up to 15 pF and ≤11.0 ns up to 50 pF (over full temperature range). For loads >50 pF, output rise/fall times increase significantly, risking setup/hold violations in synchronous circuits - external buffering is recommended beyond this limit.

Can Pin 1 (n.c.) be connected to GND or VCC?

Pin 1 is internally unconnected and must remain floating or be tied to GND per Nexperia's layout recommendations. Connecting it to VCC creates a potential leakage path and violates the absolute maximum rating for input voltage (VI ≤ VCC + 0.5 V). Grounding is acceptable and improves mechanical stability but adds no electrical benefit.

Does this part support hot-swap or live-insertion?

No - the 74AHC1G04GW,125 lacks explicit hot-swap protection features such as power-on reset, I²C-style bus hold, or controlled output enable. While its overvoltage-tolerant inputs improve robustness during partial power-up, uncontrolled insertion into a live backplane risks latch-up or transient overstress due to supply sequencing mismatch.
