Product details
Overview
74AHCT00D,118 from Nexperia is a quad 2-input NAND gate IC with TTL-compatible input thresholds, operating from 4.5 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, balanced propagation delays (typ. 3.3 ns at 5 V, 15 pF), and guaranteed operation from –40 °C to +125 °C in SO14 package. It serves as a level-translating logic buffer in mixed-voltage digital control subsystems such as industrial PLC I/O modules.
For engineers reviewing the 74AHCT00D,118 datasheet, 74AHCT00D,118 pinout, 74AHCT00D,118 application, or 74AHCT00D,118 equivalent, key selection criteria include TTL-level input compatibility, SO14 thermal performance at 125 °C ambient, output drive capability (±8 mA), Schmitt-trigger input hysteresis, and overvoltage tolerance for interfacing with legacy 5 V systems.
Technical Context
This device implements four independent NAND gates in a single monolithic CMOS structure with TTL-compatible input voltage thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail CMOS output swing. Each gate exhibits matched propagation delay (tPLH ≈ tPHL) and supports simultaneous switching of all four gates under load.
The SO14 package (SOT108-1) provides 14-pin plastic small outline construction with 3.9 mm body width, 1.27 mm lead pitch, and specified thermal derating (10.1 mW/K above 100 °C), enabling use in high-reliability industrial control boards where board space and thermal margin are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - enables compact implementation of combinational logic, enable/disable control, and signal inversion in multi-channel systems. |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-signal microcontroller interfaces without level-shifting circuitry. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL logic levels across temperature and voltage variation. |
| Propagation Delay | 3.3 ns (typ), 9.0 ns (max) at VCC = 5 V, CL = 15 pF - supports >100 MHz toggle rates in synchronous control paths with predictable timing margins. |
| Output Drive | ±8 mA at VOH/VOL - sufficient to directly drive multiple 74-series inputs or LED indicators without external buffers. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive ECUs, motor drives, and industrial automation environments. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and board assembly in uncontrolled environments. |
Pinout & Package
74AHCT00D,118 is housed in a 14-lead SO14 (SOT108-1) plastic small outline package with 3.9 mm body width, 1.27 mm lead pitch, and exposed pad not present. Pin 1 is marked by a notch or index area on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data Input A | Four independent first inputs per NAND gate; overvoltage tolerant to 5.5 V regardless of VCC. |
| 1B, 2B, 3B, 4B | Data Input B | Four independent second inputs per NAND gate; each features Schmitt-trigger action for noise immunity on slow-rising signals. |
| 1Y, 2Y, 3Y, 4Y | Data Output | Active-low NAND outputs; capable of sourcing/sinking ±8 mA while maintaining VOH ≥ 3.7 V and VOL ≤ 0.55 V at full load. |
| 7 | GND | Ground reference (0 V); must be low-impedance connection to minimize ground bounce in multi-gate switching. |
| 14 | VCC | Positive supply input; decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min, VIL = 0.8 V max at 5 V - eliminates need for external level shifters when interfacing with legacy 5 V microcontrollers or peripheral ICs. |
| Overvoltage-tolerant inputs | Withstand up to 5.5 V regardless of VCC setting - enables safe connection to higher-voltage buses (e.g., 5 V I²C pull-ups) without clamping diodes. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V typical - suppresses chatter on noisy or slowly transitioning control lines (e.g., front-panel switches, sensor outputs). |
| Balanced propagation delays | tPLH and tPHL match within 0.5 ns (typ) - critical for glitch-free enable/disable sequencing in clock gating or bus arbitration logic. |
| Wide temperature range | Specified from –40 °C to +125 °C - supports deployment in engine control units, power inverters, and outdoor telecom equipment without derating. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT00PW,118 | TSSOP14 package (SOT402-1), 4.4 mm body width, 0.65 mm pitch - lower profile and improved thermal resistance (7.3 mW/K derating above 81 °C). | Better suited for space-constrained PCB layouts and higher-density routing; requires finer-pitch reflow profile. | Select when board height is limited or thermal dissipation at elevated ambient exceeds SO14 capability. |
| SN74AHCT00DR | Texas Instruments variant in SO14; identical logic function and DC specs, but VIH/VIL tighter (VIH = 2.0 V min, VIL = 0.8 V max same), slightly higher ICC (max 40 μA vs. 20 μA at 5.5 V). | Valid drop-in replacement for TI-based designs; same pinout and footprint, but higher static current may affect battery-powered sleep modes. | Select only when TI qualification or existing BOM alignment is required; otherwise prefer Nexperia for lower ICC and broader temp range certification. |
Compared with 74AHCT00PW,118, the 74AHCT00D,118 offers superior mechanical robustness and easier hand-soldering, while SN74AHCT00DR trades marginal static current increase for TI ecosystem compatibility-neither matches the 74AHCT00D,118's combination of 125 °C rating, SO14 manufacturability, and 20 μA max ICC.

FAQ
Is 74AHCT00D,118 compatible with 3.3 V microcontroller outputs?
No-74AHCT00D,118 has TTL input thresholds (VIH ≥ 2.0 V), so it will reliably recognize 3.3 V logic HIGH, but its minimum recommended VCC is 4.5 V. Operating below 4.5 V violates recommended conditions and risks incorrect logic interpretation or increased propagation delay. Use 74AHC00D,118 for true 3.3 V–5.5 V operation.
Can 74AHCT00D,118 drive a 50 pF capacitive load at 10 MHz?
Yes-its typical propagation delay remains 4.5 ns at 5 V and 50 pF, and output drive strength (±8 mA) ensures clean edges into 50 pF. Total dynamic power (PD = CPD × VCC² × fi × N) stays below 1.5 mW per gate at 10 MHz, well within the SO14 package's 500 mW total power limit at 25 °C ambient.
What is the significance of "overvoltage-tolerant inputs" in this device?
Inputs tolerate up to 5.5 V regardless of VCC value-even if VCC is 3.3 V or unpowered-without damage or leakage. This allows safe connection to 5 V buses (e.g., I²C pull-ups, legacy sensor outputs) without external protection diodes, simplifying mixed-voltage board design and improving reliability in hot-swap scenarios.
Does 74AHCT00D,118 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 logic states, and potential oscillation due to noise coupling. Each unused input draws <0.1 μA when tied, versus >10 μA when floating, and avoids metastability in downstream logic paths.
