Product details
Overview
74AHCT1G00GV,125 from Nexperia is a single 2-input NAND gate with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), operating from 4.5 V to 5.5 V, rated for -40 °C to +125 °C, and housed in the SC-74A (SOT753) 5-pin surface-mount package. It serves as a level-shifting logic buffer in mixed-voltage digital control paths, such as microcontroller I/O expansion or FPGA configuration interface conditioning.
For engineers reviewing the 74AHCT1G00GV,125 datasheet, 74AHCT1G00GV,125 pinout, 74AHCT1G00GV,125 application, or 74AHCT1G00GV,125 equivalent, key selection criteria include TTL-level input compatibility, propagation delay ≤8.0 ns (CL = 50 pF, VCC = 5 V), output drive capability (±8 mA), overvoltage-tolerant inputs up to 5.5 V, and industrial temperature support.
Technical Context
This device implements a standard 2-input NAND Boolean function (Y = NOT(A AND B)) using CMOS transistor topology with TTL-level input stage design. Its input threshold is fixed near 1.4 V (VIH = 2.0 V, VIL = 0.8 V), enabling direct interfacing with legacy 5 V TTL outputs without external biasing.
Propagation delays are balanced (tPLH ≈ tPHL), output impedance is symmetrical, and the device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC - allowing safe operation when driven by higher-voltage signals in voltage-translating configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G00GW,125 | Same logic function and electrical specs, but in TSSOP5 (SOT353-1) package - 2.2 mm × 1.3 mm, 1.25 mm body width | Higher thermal resistance (Ptot derates above 74 °C); less suitable for high-density layouts requiring minimal footprint | Select when board assembly uses TSSOP-compatible pick-and-place tooling or requires slightly better thermal performance than SC-74A |
| SN74LVC1G00DBVR | CMOS-input variant (VIH = 70% VCC), wider supply range (1.65–5.5 V), lower typical propagation delay (4.5 ns @ 3.3 V) | Not TTL-compatible - cannot directly replace 74AHCT1G00GV in legacy 5 V TTL systems without redesign | Choose for new 3.3 V or dual-supply designs where input threshold flexibility and lower power are prioritized over TTL interoperability |
Compared with 74AHCT1G00GV,125, the GW variant offers identical logic and voltage specs but differs in package thermal profile and board space; the SN74LVC1G00DBVR enables broader supply adaptability and faster switching at lower voltages but sacrifices direct TTL-level compatibility required in legacy 5 V control systems.

FAQ
Is 74AHCT1G00GV,125 pin-compatible with 74AHC1G00GV?
Yes - both share identical SC-74A (SOT753) pinout (A, B, GND, Y, VCC), same footprint, and identical functional diagram. The sole difference is input threshold: AHCT uses TTL-compatible levels (VIH = 2.0 V), while AHC uses CMOS levels (VIH = 0.7×VCC). Interchange is electrically valid only if driving source logic families match the target input specification.
What is the maximum capacitive load this device can drive reliably?
74AHCT1G00GV,125 is characterized up to 50 pF load capacitance, with propagation delay specified at ≤8.0 ns under those conditions. Driving >50 pF increases delay nonlinearly and may cause marginal timing in high-speed interfaces; for loads >75 pF, consider buffering or reducing trace length and adding series termination.
Does this part require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied HIGH or LOW via direct connection to VCC or GND. Floating inputs are prohibited due to CMOS topology risk of increased ICC, shoot-through current, and unpredictable output states. Internal protection diodes do not eliminate this requirement.
Can 74AHCT1G00GV,125 operate with VCC = 3.3 V?
No - the 74AHCT variant is specified only for VCC = 4.5 V to 5.5 V. At 3.3 V, VIH (2.0 V) exceeds 60% of VCC, violating input threshold ratio requirements and risking unreliable HIGH detection. For 3.3 V systems, use 74AHC1G00GV or 74LVC1G00 instead.
