Product details
Overview
74AC00SC from ON Semiconductor is a quad 2-input NAND gate IC in 14-lead SOIC (M14A) package, operating at 2.0–6.0V supply, delivering 24mA output drive, 6.0ns typical propagation delay at 5V, and ±50mA absolute max output current. It serves as a fundamental logic building block in digital control, interface buffering, and signal conditioning circuits.
For engineers reviewing the 74AC00SC datasheet, pinout, applications, or equivalent options, key selection considerations include AC-series CMOS input thresholds, rail-to-rail output swing, low ICC quiescent current (≤20µA), and compatibility with 3.3V/5V mixed-signal systems.
Technical Context
The 74AC00SC implements four independent 2-input NAND gates using advanced CMOS technology, supporting TTL- and CMOS-level compatible inputs without requiring external pull-ups. Its logic threshold scales with VCC (VIH = 0.7×VCC min, VIL = 0.3×VCC max), enabling robust noise immunity across 3.3V and 5V domains.
It features symmetrical output drive (24mA sink/source), low dynamic power dissipation (CPD = 30pF), and guaranteed operation from –40°C to +85°C. Input capacitance is 4.5pF, and minimum input edge rate is 125mV/ns - critical for clean switching in high-speed combinatorial logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND - enables compact implementation of basic Boolean logic, reset generation, and enable/disable control in digital subsystems |
| Supply Voltage Range | 2.0V to 6.0V - supports direct interfacing with both 3.3V and 5V logic families without level shifters |
| Propagation Delay (tPLH/tPHL) | 6.0ns typical at VCC = 5.0V, CL = 50pF - ensures timing predictability in synchronous control and clocked state machines |
| Output Drive Capability | ±24mA per output - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74AC/ACT inputs without buffers |
| Quiescent Supply Current (ICC) | ≤20µA at VCC = 5.5V - minimizes standby power in battery-backed or energy-sensitive embedded control applications |
| Input Thresholds | VIH ≥ 2.1V, VIL ≤ 0.9V at VCC = 3.0V - provides 1.2V noise margin under nominal 3.3V operation |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade deployment in programmable logic controllers and motor control interfaces |
Pinout & Package
74AC00SC uses a 14-lead SOIC package (JEDEC MS-012, 0.150" narrow body, M14A), with standard dual-in-line pin spacing (1.27mm pitch) and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input (A1/B1, A2/B2, A3/B3, A4/B4) | Four independent NAND gate inputs - each pair (e.g., pins 1&2) feeds one gate; CMOS-compatible, high-impedance |
| 3, 6, 10, 13 | Output (Y1, Y2, Y3, Y4) | Active-low NAND outputs - rail-to-rail swing, capable of sourcing/sinking 24mA while maintaining VOL ≤ 0.44V |
| 7 | GND | Ground reference for all logic and power domains - must be low-inductance connection to minimize switching noise |
| 14 | VCC | Positive supply input - decoupling capacitor (0.1µF ceramic) required within 5mm for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|

| High Output Drive | ±24mA per output enables direct driving of 10+ 74AC inputs or discrete loads without external buffers |
| Voltage-Tolerant Inputs | Accepts 0–6.0V input signals regardless of VCC - simplifies mixed-voltage interconnect and hot-swap interface design |
| Fast Propagation Delay | 6.0ns typical tPLH/tPHL at 5V allows use in <100MHz clock domain edge detection and combinatorial glue logic |
| JEDEC-Compliant SOIC | M14A package meets MS-012 mechanical standards - ensures compatibility with automated SMT assembly and IPC-7351 land patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74ACT00SC | TTL-compatible inputs (VIH = 2.0V min, VIL = 0.8V max at 5V); identical SOIC-14 package and pinout | Better suited for interfacing with legacy 5V TTL outputs; slightly higher ICC (≤1.5mA per input) | Select when connecting to 74LS/74F series or other TTL sources; not recommended for pure CMOS systems due to reduced noise margin |
| SN74AC00DR | Same AC logic family, identical electrical specs, but TI-manufactured with different SOIC-14 footprint (same JEDEC MS-012 outline) | Validated for automotive AEC-Q100 Grade 3; broader qualification documentation available | Prefer for automotive or extended-temperature designs requiring full AEC-Q100 traceability and PPAP support |
Compared with 74AC00SC, 74ACT00SC offers tighter input thresholds for TTL interoperability but higher static current, while SN74AC00DR delivers identical logic performance with automotive-grade process control and qualification - choice depends on interface source type and end-market compliance requirements.

FAQ
What is the maximum operating supply voltage for the 74AC00SC?
The 74AC00SC supports a recommended operating supply voltage range of 2.0V to 6.0V. Its absolute maximum rating is +7.0V, but sustained operation above 6.0V risks exceeding safe junction temperature and violates the manufacturer's recommended conditions. For reliable long-term use in industrial environments, 5.0V or 3.3V operation is typical - both fully supported with guaranteed VIH/VIL thresholds and propagation delays specified in the datasheet.
Does the 74AC00SC have TTL-compatible inputs?
No, the 74AC00SC does not have TTL-compatible inputs. It uses standard CMOS input thresholds (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC). In contrast, the 74ACT00SC variant - which shares the same SOIC-14 package - features TTL-compatible inputs (VIH = 2.0V min, VIL = 0.8V max at VCC = 5V). This distinction is critical when interfacing with legacy 74LS or 74F outputs, where the 74AC00SC may exhibit marginal noise immunity.
Can the 74AC00SC drive an LED directly?
Yes, the 74AC00SC can drive a standard 20mA LED directly in sink configuration (anode to VCC, cathode to output pin), as its guaranteed output sink current is 24mA at VOL ≤ 0.44V. For source-mode driving (cathode to GND, anode to output), it also provides 24mA with VOH ≥ 4.4V at VCC = 4.5V. Always include a series current-limiting resistor calculated for the specific LED forward voltage and desired current.
Is the 74AC00SC pin-compatible with the 74HC00?
Yes, the 74AC00SC is pin-compatible with the 74HC00 in the same SOIC-14 package (M14A), sharing identical pin assignments for inputs, outputs, VCC, and GND. However, they differ electrically: the 74AC00SC offers faster propagation delay (~6ns vs ~15ns), higher output drive (±24mA vs ±4mA), and wider VCC range (2–6V vs 2–6V, but HC optimized for 4.5–5.5V). Substitution is functionally valid but requires verifying timing and drive requirements.
What is the input capacitance of the 74AC00SC?
The input capacitance (CIN) of the 74AC00SC is 4.5pF per input pin, measured with VCC open-circuit at TA = +25°C. This low value minimizes loading on upstream drivers and supports high-frequency signal integrity in fan-out-heavy configurations. When designing PCB layouts, keep input traces short and avoid stubs to prevent resonance effects, especially in systems operating near the device's 125mV/ns minimum input edge rate requirement.
