NXP Semiconductors 74AHC2G08GD,125

Overview

74AHC2G08GD,125 from Nexperia is a dual 2-input AND gate logic IC in XSON8 (SOT996-2) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, CMOS-level input thresholds, and propagation delay as low as 3.2 ns (VCC = 5.0 V, CL = 15 pF). It enables voltage translation in mixed-supply systems such as I²C level-shifting interfaces and microcontroller GPIO expansion.

For engineers reviewing the 74AHC2G08GD,125 datasheet, 74AHC2G08GD,125 pinout, 74AHC2G08GD,125 application, or 74AHC2G08GD,125 equivalent, this device is selected for low-power, high-speed dual-gate logic in space-constrained industrial control, portable instrumentation, and FPGA companion logic where input tolerance and rail-to-rail compatibility are critical.

Technical Context

This device implements two independent AND gates in a single monolithic CMOS structure, with symmetrical output drive capability (±8 mA at VCC = 4.5 V) and balanced tPLH/tPHL propagation delays. Its overvoltage-tolerant inputs support interfacing between 1.8 V/2.5 V logic domains and 3.3 V/5 V buses without external clamping.

The logic function conforms strictly to IEEE Std 91-1984 and IEC 60617-12, with static input thresholds defined at VIH ≥ 3.85 V and VIL ≤ 1.65 V (VCC = 5.5 V), and dynamic performance characterized across -40 °C to +125 °C ambient temperature range under load capacitances of 15 pF and 50 pF.

FAQ

Is 74AHC2G08GD,125 pin-compatible with 74AHCT2G08GD,125?

Yes - both share identical XSON8 (SOT996-2) pinout and mechanical footprint. However, 74AHCT2G08GD,125 uses TTL-compatible input thresholds (VIH = 2.0 V min), while 74AHC2G08GD,125 requires CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V). Swapping requires verifying upstream driver compatibility.

What is the maximum allowable input voltage when VCC = 2.0 V?

The absolute maximum input voltage is 5.5 V, independent of VCC level. This overvoltage tolerance is guaranteed per datasheet Section 2 and Table 5, enabling safe interface with 5 V signals even when powered from 2.0 V - a key feature for mixed-voltage translation.

Does 74AHC2G08GD,125 require external pull-up resistors on inputs?

No - inputs are CMOS-compatible with high-impedance, low-leakage (<0.1 μA) behavior. Pull-ups are only needed if the driving source is open-drain or if a defined logic state is required during power-up/reset; unused inputs must be tied HIGH or LOW to prevent floating.

Can this device operate reliably at 125 °C junction temperature?

Yes - the device is fully characterized and guaranteed over -40 °C to +125 °C ambient temperature (Tamb), with derated power dissipation applied per datasheet Section 8. At Tamb = 125 °C, total power must remain ≤ 250 mW, and thermal design must maintain TJ ≤ 150 °C using the θJA of the XSON8 package.
