Product details
Overview
74AHCT3G04DC from Nexperia is a triple CMOS inverter with TTL-compatible input thresholds, designed for level translation in 5 V mixed-signal systems. It operates from 4.5 V to 5.5 V, delivers ±8 mA output drive, exhibits 3.4 ns (min) to 8.5 ns (max) propagation delay at 5 V/15 pF, and supports -40 °C to +125 °C ambient operation - used in industrial control logic buffering and microcontroller I/O signal inversion.
For engineers reviewing the 74AHCT3G04DC datasheet, 74AHCT3G04DC pinout, 74AHCT3G04DC application, or 74AHCT3G04DC equivalent, key selection criteria include TTL-level input compatibility, overvoltage-tolerant inputs up to 5.5 V, VSSOP8 package footprint constraints, and guaranteed 125 °C operation for harsh-environment digital interfacing.
Technical Context
This device implements three independent inverting buffers with rail-to-rail CMOS outputs and fixed TTL-switching thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V). Input pins tolerate up to 5.5 V regardless of supply voltage, enabling safe interfacing between 3.3 V controllers and 5 V peripherals.
Propagation delays are characterized across temperature and load: tPD = 3.4–8.5 ns (CL = 15 pF) and 4.9–10.0 ns (CL = 50 pF) over -40 °C to +125 °C. Output drive strength is symmetrical (IOH = -8 mA, IOL = 8 mA), ensuring matched rise/fall times and low skew in timing-critical paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V logic rails and tolerance against supply ripple. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - meets TTL input compatibility requirements for legacy system integration. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive 15 pF loads with <10 ns delay and interface multiple 74-series inputs. |
| Propagation Delay | 3.4 ns (min) to 8.5 ns (max) at CL = 15 pF - enables use in sub-100 MHz clock distribution and data path inversion. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLCs, and high-reliability embedded control. |
| Input Overvoltage Tolerance | 5.5 V absolute max on all inputs - allows safe connection to higher-voltage buses without external clamping. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package; 8 leads; body width 2.3 mm; pin pitch 0.5 mm; exposed pad not present; JEDEC MO-187 compliant (SOT765-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A1 | First inverter input; accepts TTL/CMOS levels; overvoltage tolerant to 5.5 V. |
| 2 | Output Y3 | Third inverter output; drives loads up to ±8 mA with rail-to-rail swing. |
| 3 | Input A2 | Second inverter input; electrically identical to Pin 1; shares same noise immunity. |
| 4 | GND | Digital ground reference; must be low-impedance connection to minimize switching noise. |
| 5 | Output Y2 | Second inverter output; matched delay and drive to Pins 2 and 7 for balanced timing. |
| 6 | Input A3 | Third inverter input; fully decoupled from other inputs; supports independent signal routing. |
| 7 | Output Y1 | First inverter output; inverted logic state of Pin 1; used for primary signal path inversion. |
| 8 | VCC | Positive supply; requires local 100 nF ceramic decoupling within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | Enables direct replacement of 74LS04 in legacy 5 V systems without level-shifter redesign. |
| Overvoltage-tolerant inputs | Accepts 5.5 V signals while powered from 4.5 V - eliminates need for external clamping diodes in mixed-voltage nodes. |
| Symmetrical output impedance | Matches rise/fall times (tPLH ≈ tPHL), reducing jitter in clock inversion and data path applications. |
| High noise immunity | Input hysteresis margin > 1.2 V at VCC = 5 V - suppresses false triggering from EMI or crosstalk in noisy industrial environments. |
| Low static power consumption | ICC ≤ 1.0 μA typical at VCC = 5.5 V - suitable for always-on logic monitoring circuits with strict quiescent current budgets. |
Applications
| Industrial PLC I/O Conditioning | Microcontroller GPIO Signal Inversion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC3G04DC | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); wider 2.0–5.5 V supply range. | Better suited for mixed 3.3 V/5 V systems requiring bidirectional level translation. | Select when interfacing with 3.3 V controllers driving 5 V loads - not TTL-compatible. |
| SN74LVC3G04DCUR | 3.3 V only (1.65–3.6 V); lower VCC max; LVTTL thresholds; smaller X2SON8 package (1.0 × 1.5 mm). | Optimized for ultra-compact portable electronics; incompatible with 5 V signaling. | Choose for space-constrained 3.3 V designs where 5 V tolerance is unnecessary. |

FAQ
Is the 74AHCT3G04DC pin-compatible with the 74LS04?
No - the 74AHCT3G04DC is a triple inverter (3 gates) in an 8-pin VSSOP package, whereas the 74LS04 is a hex inverter (6 gates) in a 14-pin DIP/SO package. However, its electrical behavior (TTL input thresholds, 5 V operation, ±8 mA drive) matches 74LS04 per gate, enabling functional substitution where only three inverters are required and board layout permits VSSOP8 placement.
Can the 74AHCT3G04DC operate reliably at 4.5 V supply?
Yes - the datasheet specifies guaranteed operation from 4.5 V to 5.5 V across -40 °C to +125 °C. At VCC = 4.5 V, VOH ≥ 3.94 V (IOH = -8 mA), VOL ≤ 0.36 V (IOL = 8 mA), and tPD ≤ 8.5 ns (CL = 15 pF), meeting all TTL output voltage and timing requirements for interoperability with legacy 5 V logic families.
What is the maximum capacitive load the 74AHCT3G04DC can drive while maintaining timing specs?
The device is characterized up to 50 pF load capacitance: tPD = 4.9–10.0 ns (min/max) at VCC = 4.5–5.5 V and -40 °C to +125 °C. Driving >50 pF increases delay nonlinearly and may cause excessive shoot-through current; for >50 pF loads, add series termination or use a buffer with higher drive strength.
Does the 74AHCT3G04DC require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be terminated to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable output states, and potential oscillation due to noise coupling. The device lacks internal input bias; a 10 kΩ resistor to VCC or GND is recommended for each unconnected input to ensure stable logic levels and minimize power waste.
