Product details
Overview
74HCT00D/AUJ from Nexperia is a quad 2-input NAND gate logic IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, 12 ns typical propagation delay at VCC = 4.5 V, ±4 mA output drive, and SO14 (SOT108-1) package. It performs basic Boolean NAND logic in digital control, address decoding, and enable gating circuits for industrial microcontroller peripherals.
For engineers reviewing the 74HCT00D/AUJ datasheet, 74HCT00D/AUJ pinout, 74HCT00D/AUJ application, or 74HCT00D/AUJ equivalent, this page delivers verified functional identity, SO14 pin mapping, TTL-level interface behavior, temperature-rated static/dynamic specs (-40 °C to +125 °C), and validated alternative options for logic gate replacement in legacy and new designs.
Technical Context
The 74HCT00D/AUJ implements four independent CMOS-based NAND gates using silicon-gate technology with buffered outputs. Each gate accepts two TTL-level inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and delivers rail-to-rail CMOS-compatible outputs with 4 mA sink/source capability.
It operates within a strict 4.5–5.5 V supply window and supports full industrial temperature range (-40 °C to +125 °C). Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors, and latch-up immunity exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - four independent gates, each computing Y = NOT(A AND B) |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V TTL systems; not rated below 4.5 V |
| Propagation Delay | 12 ns typical (VCC = 4.5 V, CL = 50 pF) - enables reliable timing in ≤30 MHz combinatorial logic paths |
| Output Drive | ±4 mA - sufficient to directly drive multiple 74-series TTL inputs or small LEDs with series resistor |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - ensures robust noise margin and compatibility with legacy 5 V TTL outputs |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor control, and industrial PLC environments |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 for handling in automated assembly |
Pinout & Package
74HCT00D/AUJ uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | Independent NAND gate input A terminals - accept TTL-level signals; internally clamped |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Independent NAND gate input B terminals - paired with corresponding A inputs per gate |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Independent NAND gate outputs - CMOS rail-to-rail swing, capable of sourcing/sinking 4 mA |
| 7 | GND | Ground reference (0 V) - must be connected to system common; decoupling capacitor recommended |
| 14 | VCC | Positive supply (4.5–5.5 V) - requires local 100 nF ceramic decoupling near pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - eliminates level-shifting when interfacing with legacy 74LS/74F devices |
| Clamp diode protection | Integrated input diodes allow safe connection to signals up to VCC + 0.5 V using external current-limiting resistors |
| High noise immunity | Typical 1.2 V DC noise margin at VCC = 5 V - suppresses false triggering in electrically noisy industrial environments |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive parasitic thyristor activation during transient overvoltage |
| Wide temperature range | Specified from -40 °C to +125 °C - supports operation in automotive engine compartments and industrial motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT00PW | TSSOP14 package (SOT402-1); 4.4 mm body width; 0.65 mm pitch; same electrical specs | Higher density layout; requires reflow profile adjustment for thinner package; no lead coplanarity risk | Select for space-constrained boards where SO14 footprint is unavailable |
| SN74HCT00DR | Texas Instruments part; identical function, pinout, and DC specs; propagation delay 13 ns (typ) at 5 V | Same SO14 mechanical fit; different ESD rating (HBM >4000 V); longer lead-time in some regions | Choose for dual-sourcing where TI qualification is mandated or preferred |
Compared with 74HCT00D/AUJ, the 74HCT00PW offers miniaturization at the cost of thermal dissipation margin, while SN74HCT00DR provides second-source assurance with marginally higher ESD robustness but identical functional behavior in circuit design.

FAQ
What is the supply voltage range for the 74HCT00D/AUJ?
The 74HCT00D/AUJ operates strictly within 4.5 V to 5.5 V. Unlike the 74HC00 variant, it is not specified below 4.5 V due to its TTL-compatible input threshold design. Operation outside this range may result in undefined logic states or degraded noise immunity. Always use a regulated 5 V supply with local 100 nF ceramic decoupling at the VCC pin for stable 74HCT00D/AUJ performance.
Does the 74HCT00D/AUJ support operation at -40 °C to +125 °C?
Yes, the 74HCT00D/AUJ is fully specified and tested across -40 °C to +125 °C ambient temperature. This rating applies to all key parameters including propagation delay, output drive, and input thresholds. The SO14 package (SOT108-1) and internal die design meet Nexperia's industrial-grade thermal qualification standards, making the 74HCT00D/AUJ suitable for under-hood automotive modules and industrial motor drives.
Can the 74HCT00D/AUJ interface directly with 3.3 V microcontroller GPIOs?
No - the 74HCT00D/AUJ inputs require VIH ≥ 2.0 V (min) and VIL ≤ 0.8 V (max) at VCC = 4.5–5.5 V, so a 3.3 V logic HIGH may not reliably register as valid HIGH input. Direct connection risks metastability or incorrect logic evaluation. Use a level translator or select the 74LVC00 for true 3.3 V–5 V bidirectional interfacing. The 74HCT00D/AUJ is intended for 5 V TTL system integration.
What is the maximum output current per pin on the 74HCT00D/AUJ?
The 74HCT00D/AUJ delivers ±4 mA per output pin under recommended operating conditions (VCC = 4.5–5.5 V, Tamb = -40 °C to +125 °C). This is verified in the Static Characteristics table for VOH and VOL. Exceeding ±4 mA risks violating VOL ≤ 0.4 V or VOH ≥ 3.7 V specifications and may accelerate parametric drift over temperature and lifetime. For higher drive, buffer with a transistor or dedicated driver IC.
Is the 74HCT00D/AUJ pin-compatible with the 74HC00D?
Yes - the 74HCT00D/AUJ and 74HC00D share identical SO14 pinout, terminal numbering, and logic function. However, their input voltage thresholds differ: 74HC00D uses CMOS thresholds (VIH ≈ 0.7×VCC), while 74HCT00D/AUJ uses fixed TTL thresholds (VIH = 2.0 V min). Swapping them requires verifying source logic levels; the 74HCT00D/AUJ will not correctly interpret 3 V HIGH signals that suffice for 74HC00D.
