Product details
Overview
74AHCT04D,112 from Nexperia is a hex inverter IC in SO14 package, implementing six independent CMOS-compatible TTL-level inverting buffers with 5 V supply operation, propagation delay ≤7.0 ns (CL = 15 pF), and output drive capability of ±8 mA. It serves as level-shifting signal inversion logic in microcontroller I/O expansion, bus buffering, and clock signal conditioning circuits.
For engineers reviewing the 74AHCT04D,112 datasheet, 74AHCT04D,112 pinout, 74AHCT04D,112 application, or 74AHCT04D,112 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), guaranteed operation from –40 °C to +125 °C, SO14 package thermal performance, and static current <40 μA at VCC = 5.5 V.
Technical Context
The 74AHCT04D,112 uses silicon-gate CMOS technology with TTL-level input circuitry, enabling direct interfacing with legacy LSTTL outputs while maintaining CMOS power efficiency. Its inputs accept voltages up to 5.5 V independent of VCC, and outputs swing rail-to-rail under load.
Each inverter stage features matched P- and N-channel MOSFETs for balanced tPLH/tPHL propagation delays, with typical tpd = 3.0 ns at VCC = 5.0 V and CL = 15 pF. The device complies with JEDEC Standard No. 7-A and supports hot-swap tolerant operation via input clamping diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V digital systems and noise margin compliance. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Guarantees reliable recognition of TTL logic levels across temperature. |
| Propagation Delay | tpd ≤ 7.0 ns (CL = 15 pF, VCC = 5.0 V) - Supports >100 MHz toggle rates in non-critical timing paths. |
| Output Drive | ±8.0 mA (VOH/VOL tested at IO = ±8 mA) - Sustains fan-out of ≥10 LS-TTL loads without external buffering. |
| Quiescent Current | ICC ≤ 40 μA (VCC = 5.5 V, –40 °C to +125 °C) - Enables low-power standby in always-on control logic. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Reduces handling sensitivity during PCB assembly and field service. |
| Operating Temperature | –40 °C to +125 °C - Validated for under-hood automotive modules and industrial motor drives. |
Pinout & Package
74AHCT04D,112 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and gull-wing lead form. Thermal resistance θJA = 100 K/W (JEDEC Std. 51-2, 1-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Accept TTL-level signals; internally clamped to GND/VCC; no external pull-up required. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverted logic output; capable of sourcing/sinking 8 mA while maintaining VOL ≤ 0.55 V. |
| 7 | GND | Dedicated ground reference for all internal logic and output stages; must be low-impedance. |
| 14 | VCC | Primary 5 V supply; decoupling capacitor (100 nF) recommended within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V - Eliminates need for level translators when interfacing with 74LS/74F families. |
| Balanced propagation delays | tPLH/tPHL match within 0.5 ns (typ.) - Prevents duty-cycle distortion in clock inversion or waveform shaping applications. |
| Wide temperature range | Specified from –40 °C to +125 °C - Supports deployment in engine control units and industrial PLC backplanes. |
| Low input leakage | II ≤ 2.0 μA (–40 °C to +125 °C) - Minimizes loading on high-impedance sensor interface nodes or RC timing networks. |
| Multiple package options | SO14 (SOT108-1), TSSOP14 (SOT402-1), DHVQFN14 (SOT762-1) - Enables layout flexibility across cost-, space-, and thermal-constrained designs. |

Use Value: Guaranteed 125 °C operation ensures reliability in enclosed power supply enclosures; low ICC minimizes quiescent drain on backup batteries. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC04D,112 | CMOS-input version; VIH = 3.85 V @ VCC = 5.5 V; tpd = 5.5 ns (CL = 15 pF) | Requires CMOS-level input sources; unsuitable for direct LS-TTL driving | Select when interfacing with 3.3 V or mixed-voltage logic and lowest propagation delay is critical. |
| SN74HCT04DR | TI-manufactured; identical VIH/VIL specs; tpd = 6.5 ns (CL = 15 pF); SO14 footprint compatible | Same functional behavior but different ESD rating (HBM > 4000 V) and qualification history | Preferred for TI-design ecosystems or where higher HBM robustness is mandated by internal QA policies. |

FAQ
Can 74AHCT04D,112 operate at 3.3 V supply?
No. The 74AHCT04D,112 is specified only for VCC = 4.5 V to 5.5 V per Table 5. At 3.3 V, input thresholds (VIH ≥ 2.0 V) may not be met reliably, and output drive strength degrades significantly. Use 74AHC04D,112 instead for 3.3 V systems.
Is the SO14 package RoHS-compliant and lead-free?
Yes. The 74AHCT04D,112 in SOT108-1 package conforms to RoHS Directive 2011/65/EU and is lead-free, with matte tin terminal finish and halogen-free molding compound, as confirmed in Nexperia's official product change notices.
What is the maximum capacitive load this device can drive without exceeding propagation delay specs?
The datasheet guarantees tpd ≤ 7.0 ns only up to CL = 15 pF at VCC = 5.0 V. Driving >50 pF increases tpd to ≤9.5 ns and raises dynamic power dissipation; for >50 pF loads, add a series resistor or buffer stage to maintain timing integrity.
Does this part support partial power-down or I/O isolation when VCC = 0 V?
No. The 74AHCT04D,112 lacks Ioff protection. With VCC = 0 V, input/output pins exhibit undefined leakage paths; applying signals risks back-powering internal circuitry. Use devices with Ioff specification (e.g., 74LVC04A) for hot-swap or partial-power scenarios.
