Product details
Overview
74AHCT1G04GV,125 from Nexperia is a single-channel TTL-input inverter in SC-74A (SOT753) package, operating at 4.5 V to 5.5 V supply, delivering 8 mA output drive, 3.4 ns typical propagation delay (CL = 15 pF, VCC = 5 V), and overvoltage-tolerant inputs up to 5.5 V - used for level translation and signal inversion in industrial control I/O buffers.
For engineers reviewing the 74AHCT1G04GV,125 datasheet, 74AHCT1G04GV,125 pinout, 74AHCT1G04GV,125 application, or 74AHCT1G04GV,125 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), −40 °C to +125 °C operation, symmetrical output impedance, and SC-74A thermal derating (3.8 mW/K above 85 °C).
Technical Context
This device implements a single unbuffered inverter logic function with TTL-level input switching thresholds and CMOS output structure. It supports mixed-voltage interfacing via overvoltage-tolerant inputs that accept up to 5.5 V regardless of VCC, enabling use between 5 V logic domains and higher-voltage subsystems.
Its dynamic performance is characterized by balanced tPLH/tPHL propagation delays (max 8.5 ns over −40 °C to +85 °C, CL = 15 pF), low static current (ICC ≤ 10 μA at VCC = 5.5 V), and input capacitance of 10 pF - optimized for low-noise, high-speed digital signal conditioning in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single inverter (NOT gate) with true output polarity and no internal buffering |
| Supply Voltage Range | 4.5 V to 5.5 V - restricts use to 5 V systems; not compatible with 3.3 V-only rails |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of legacy 5 V TTL signals |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive one 74-series TTL input or multiple CMOS loads |
| Propagation Delay | Typ. 3.4 ns (max 8.5 ns, −40 °C to +85 °C, CL = 15 pF) - enables >100 MHz toggle rates in clean load conditions |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood industrial and extended-range embedded applications |
| Input Overvoltage Tolerance | Inputs withstand up to 5.5 V independent of VCC - allows safe interfacing with 5 V buses while powered from regulated 5 V rail |
Pinout & Package
SC-74A (SOT753) plastic surface-mounted package: 5-terminal, 1.3 mm × 1.7 mm × 1.0 mm body, 0.65 mm lead pitch, no exposed pad, pin 1 index located below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (n.c.) | No-connect terminal | Internally unconnected; must remain floating or grounded per layout best practice - no routing or soldering required |
| 2 (A) | Input signal terminal | Accepts TTL-level digital input (0–5 V); overvoltage tolerant to 5.5 V; 10 pF input capacitance affects high-frequency edge integrity |
| 3 (GND) | Ground reference | Primary 0 V return path; must be low-inductance connection to minimize ground bounce during output switching |
| 4 (Y) | Inverted output terminal | CMOS push-pull output sourcing/sinking ±8 mA; rail-to-rail swing (0 V to VCC); matched rise/fall impedance |
| 5 (VCC) | Power supply input | 4.5–5.5 V DC supply; requires local 100 nF ceramic decoupling within 3 mm of pin to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstand 5.5 V regardless of VCC - enables safe interface with hot-pluggable or mismatched voltage domains |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures equal rise/fall times and reduced signal distortion |
| Balanced propagation delays | tPLH ≈ tPHL - minimizes duty cycle distortion in clock inversion or pulse shaping applications |
| High noise immunity | Input hysteresis not specified, but TTL thresholds and 0.8 V noise margin at VCC = 5 V reduce susceptibility to EMI |
| ESD protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 for board-level handling robustness |
Applications
| Industrial PLC I/O Module | Legacy Bus Signal Conditioning |

Use Scenario: Inverting enable signals for relay drivers and optocoupler interfaces in programmable logic controller backplanes. IC Role / Device Role / Timing Role: Single-shot logic inversion with sub-10 ns delay to synchronize 5 V control pulses across isolated zones. Use Value: TTL input compatibility ensures direct connection to microcontroller GPIO without level-shifter components; overvoltage tolerance prevents latch-up during field-wiring transients. |
Use Scenario: Cleaning and inverting RS-232 handshake lines (e.g., RTS/CTS) before feeding into modern UART peripherals. IC Role / Device Role / Timing Role: Signal polarity correction and noise filtering for bidirectional control lines operating at ≤1 Mbps. Use Value: 8 mA drive capability sustains signal integrity over 10 cm PCB traces; −40 °C to +125 °C rating supports deployment in factory-floor enclosures. |
| Automated Test Equipment (ATE) Fixture | Embedded Sensor Interface |
|
Use Scenario: Inverting test-mode select signals in boundary-scan JTAG chains where active-low assertion is required. IC Role / Device Role / Timing Role: Deterministic NOT function with guaranteed 8.5 ns max delay to maintain TCK timing budget in high-speed scan operations. Use Value: Low ICC (≤10 μA) minimizes quiescent power in always-on diagnostic circuits; SC-74A footprint saves board area in dense fixture layouts. |
Use Scenario: Inverting open-collector sensor alerts (e.g., smoke detector fault outputs) to match MCU interrupt polarity requirements. IC Role / Device Role / Timing Role: Level translation and inversion for 5 V alarm signals entering 3.3 V microcontroller GPIOs via external pull-up. Use Value: Input overvoltage tolerance eliminates risk of damage when sensor pulls line to 5 V while MCU IO is tri-stated or powered down. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G04GW,125 | TSSOP5 (SOT353-1) package: 1.25 mm body width, 0.65 mm pitch, exposed mold compound on sides | Higher thermal resistance (3.3 mW/K derating above 74 °C vs. 3.8 mW/K for GV); slightly larger footprint | Select when board assembly uses standard TSSOP reflow profiles and thermal management prioritizes package rigidity over minimal area |
| SN74LVC1G04DBVR | CMOS input thresholds (VIH = 70% VCC), 1.65–5.5 V supply range, lower ICC (≤1 μA), same SC-74A package | Supports 3.3 V and 5 V systems natively; unsuitable for pure TTL-source interfacing due to higher VIH requirement | Select when interfacing with mixed-supply MCUs and low-quiescent-power operation is critical; avoid if driving legacy TTL loads |
Compared with 74AHCT1G04GV,125, the GW variant trades thermal efficiency for mechanical robustness in pick-and-place, while the SN74LVC1G04DBVR extends voltage flexibility at the cost of TTL compatibility - choice depends on whether legacy interface fidelity or supply adaptability dominates the design priority.

FAQ
Is 74AHCT1G04GV,125 pin-compatible with 74AHC1G04GV,125?
Yes - both share identical SC-74A (SOT753) pinout: Pin 1 (n.c.), Pin 2 (A), Pin 3 (GND), Pin 4 (Y), Pin 5 (VCC). However, 74AHC1G04GV uses CMOS input thresholds (VIH = 3.85 V at VCC = 5.5 V), making it incompatible with standard TTL sources, whereas the AHCT version's 2.0 V VIH ensures full TTL interoperability.
Can 74AHCT1G04GV,125 operate at 3.3 V supply?
No - the 74AHCT1G04GV,125 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds become undefined and output drive degrades significantly; use 74AHC1G04GV or 74LVC1G04 instead for 3.3 V systems.
What is the maximum capacitive load this inverter can drive reliably?
At VCC = 5.0 V, CL = 50 pF is validated in datasheet testing (tpd max = 10.0 ns, −40 °C to +125 °C). Driving >50 pF increases propagation delay nonlinearly and may cause ringing; for >100 pF loads, add series termination or consider buffered inverters like 74AHCT1G14.
Does this device require external pull-up or pull-down resistors on input or output?
No - the input has no internal pull-up/down and must be actively driven; the output is push-pull CMOS and does not require external termination unless driving transmission lines >10 cm. Floating inputs are prohibited and will cause excessive ICC and potential oscillation.
