Product details
Overview
74AHCT2G08GD,125 from Nexperia is a dual 2-input AND gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5.5 V absolute maximum supply rating, overvoltage-tolerant inputs up to 5.5 V, and operation across –40 °C to +125 °C. It delivers balanced propagation delays (tpd = 3.6–6.2 ns @ CL = 15 pF, VCC = 5 V) and low static current (ICC ≤ 40 μA), enabling use in mixed-voltage level-shifting and noise-immune digital control paths.
For engineers reviewing the 74AHCT2G08GD,125 datasheet, 74AHCT2G08GD,125 pinout, 74AHCT2G08GD,125 application, or 74AHCT2G08GD,125 equivalent, this device serves as a robust, temperature-stable dual gate for interface logic, enable/control signal conditioning, and voltage-domain bridging in industrial PLC I/O modules, sensor interface subsystems, and microcontroller peripheral coordination circuits.
Technical Context
This device implements two independent AND gates in a single monolithic CMOS structure with TTL-level input sensitivity-ensuring compatibility with legacy 5 V TTL outputs while operating from 4.5–5.5 V supplies. Its symmetrical output impedance and balanced tPLH/tPHL ensure minimal skew between rising and falling edges.
Input overvoltage tolerance (up to 5.5 V regardless of VCC) enables safe interfacing with higher-voltage signals without external clamping. The device meets JESD78 Class II Level A latch-up immunity (>100 mA) and JEDEC JS-001 Class 2 HBM ESD protection (>2000 V), supporting reliable deployment in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input AND gate; each gate performs Boolean Y = A · B |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures stable operation across standard 5 V rail tolerances |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC2G08GW,125 | CMOS input thresholds (VIH = 0.7×VCC), 1.65–5.5 V supply range; lower ICC but no TTL compatibility | Requires 3.3 V or mixed-rail systems; unsuitable where legacy 5 V TTL drivers are present | Select when interfacing modern low-voltage logic only; avoid if upstream TTL sources exist |
| SN74LVC2G08DCUR | Same CMOS thresholds as 74LVC2G08GW; identical 1.65–5.5 V range; slightly higher tpd (4.5 ns typ @ 3.3 V) | Pinout differs (VSS/VDD swapped vs. XSON8); not drop-in compatible; requires layout revision | Choose only if TI sourcing preference or existing DCUR footprint reuse is mandatory |
Compared with 74AHCT2G08GD,125, the 74LVC2G08GW offers wider supply flexibility but lacks TTL input compatibility, while SN74LVC2G08DCUR introduces mechanical incompatibility and marginal timing degradation-making the Nexperia part optimal for robust 5 V TTL interfacing in space-constrained industrial designs.

FAQ
Is 74AHCT2G08GD,125 pin-compatible with 74AHC2G08GD,125?
Yes-both share identical XSON8 (SOT996-2) pinout, package dimensions, and terminal functions. The sole functional difference is input threshold behavior: 74AHCT2G08GD,125 uses TTL-compatible VIH/VIL (2.0 V/0.8 V), while 74AHC2G08GD,125 uses CMOS thresholds (0.5×VCC). Electrical substitution is possible only if upstream drivers meet the respective input spec.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF load capacitance per output, with tpd specified at both 15 pF and 50 pF. Driving >50 pF may increase propagation delay nonlinearly and degrade edge rate; for loads exceeding 50 pF, add a buffer stage or reduce trace length and parallel capacitance using controlled-impedance routing.
Does this device require external pull-up or pull-down resistors on unused inputs?
No-unused inputs must be terminated to VCC or GND to prevent floating states and increased ICC. The datasheet specifies that VI = VCC or GND for static current measurement; leaving inputs unconnected risks oscillation, excess power draw, and potential damage due to undefined internal node voltages.
Can 74AHCT2G08GD,125 operate from a 3.3 V supply?
No-it is specified only for 4.5 V to 5.5 V operation. At 3.3 V, TTL input thresholds (VIH ≥ 2.0 V) become invalid relative to VCC, risking misinterpretation of logic HIGH signals. For 3.3 V systems, use 74LVC2G08 or 74AUP2G08 variants instead.
