Nexperia USA Inc. 74AHC3G04GTX

Overview

74AHC3G04GTX from Nexperia is a triple CMOS inverter IC with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0–5.5 V supply range, delivering symmetrical output impedance and balanced propagation delays (typ. 3.1 ns at 5 V, CL = 15 pF). It enables level translation in mixed-voltage digital logic systems such as I²C bus buffering and microcontroller GPIO signal inversion.

For engineers reviewing the 74AHC3G04GTX datasheet, 74AHC3G04GTX pinout, 74AHC3G04GTX application, or 74AHC3G04GTX equivalent, this device is selected for low-power, high-noise-immunity signal inversion where input voltage tolerance and rail-to-rail output swing are required in space-constrained industrial control and portable electronics designs.

Technical Context

The 74AHC3G04GTX implements three independent CMOS inverter gates in a single XSON8 package. Its inputs tolerate up to 5.5 V regardless of VCC, enabling bidirectional level shifting between 1.8 V, 3.3 V, and 5 V domains without external components.

It features TTL-compatible output drive strength (±8 mA at VCC = 4.5 V), CMOS input thresholds (VIH = 3.85 V min at VCC = 5.5 V), and operates across –40 °C to +125 °C ambient temperature, supporting robust operation in extended-temperature embedded systems.

FAQ

Is 74AHC3G04GTX pin-compatible with other 74AHC3G04 variants in different packages?

Yes - all 74AHC3G04 variants (DP, DC, GT) share identical pin functions and logic behavior. The XSON8 (GT) variant uses the same pin numbering and terminal assignment as TSSOP8 and VSSOP8 versions, enabling drop-in replacement across packages without schematic or firmware changes.

Can 74AHC3G04GTX safely interface a 5 V microcontroller output with a 3.3 V FPGA input?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V while powered from 3.3 V, allowing direct connection of 5 V logic outputs to its inputs. The output swings rail-to-rail (0 V to 3.3 V), making it compatible with 3.3 V FPGA I/O standards without external resistors or level shifters.

What is the maximum capacitive load this device can drive while maintaining specified propagation delay?

At VCC = 5 V, the datasheet specifies tpd ≤ 7.0 ns for CL = 15 pF and ≤ 9.5 ns for CL = 50 pF. Driving loads beyond 50 pF increases delay nonlinearly and may cause marginal timing closure; for >50 pF, consider buffer staging or reduced switching frequency.

Does 74AHC3G04GTX require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied to VCC or GND to prevent floating states and excessive ICC. The device has no internal termination; leaving inputs unconnected risks increased power consumption, noise susceptibility, and potential oscillation due to high-impedance CMOS inputs.
