Product details
Overview
MC74AC00N from onsemi is a quad 2-input NAND gate in silicon-gate CMOS technology, operating across 2.0–6.0 V supply, delivering ±24 mA output drive, with propagation delays as low as 1.5 ns (tPHL at 5.0 V), and used in digital logic interfacing, address decoding, and control signal conditioning in industrial and embedded systems.
For engineers reviewing the MC74AC00N datasheet, pinout, applications, or equivalent options, key selection considerations include its wide VCC range (2–6 V), rail-to-rail input thresholds, guaranteed 24 mA sink/source capability, and compatibility with both TTL- and CMOS-level input signals in mixed-voltage logic designs.
Technical Context
This device implements four independent NAND gates in a single 14-pin SOIC package, each with identical truth table Y = A·B̅ and no internal feedback or latching behavior. It uses standard CMOS transistor pairs per gate, with chip complexity specified as 32 FETs.
Input thresholds scale with VCC (VIH = 2.1 V min at 3.0 V, 3.15 V at 4.5 V), enabling interoperability across 3.3 V and 5 V domains. Output voltage levels meet JEDEC Std. 7A, with VOL ≤ 0.1 V at IOL = 24 mA and VOH ≥ 4.4 V at IOH = −24 mA under 5.5 V operation.

Pinout & Package
MC74AC00N is supplied in a 14-lead SOIC package (Case 751A), with 1.27 mm pitch, 8.75 mm × 3.90 mm body, and Pb-free finish. Pin 1 is index-marked; pin 7 is GND; pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 input | First input of Gate 1 - accepts CMOS- or TTL-compatible logic levels |
| 2 | B1 input | Second input of Gate 1 - electrically isolated from other gate inputs |

| 4 | A2 input | First input of Gate 2 - shares no internal connection with Gate 1 |
| 5 | B2 input | Second input of Gate 2 - fully independent signal path |
| 6 | Y2 output | Inverted AND of pins 4 and 5 - same DC/AC specs as Y1 |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry - must be low-impedance |
| 8 | Y3 output | Output of Gate 3 - matches Y1/Y2 performance and loading behavior |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC00N | Identical logic function, AC electrical specs, and SOIC-14 footprint; manufactured by Texas Instruments | No difference in timing, drive, or voltage range; TI's version has separate thermal resistance spec (110 °C/W vs. onsemi's 116 °C/W) | Select SN74AC00N only if dual-sourcing or TI-specific qualification is required; otherwise MC74AC00N offers identical performance. |
| 74VHC00N | Higher speed (tPD ≈ 5.5 ns typ at 5 V), lower ICC (2 µA max), but narrower VCC range (2–5.5 V) and reduced output drive (±8 mA) | Suitable for ultra-low-power portable devices where speed margin is acceptable, but insufficient for driving TTL loads or long traces | Choose 74VHC00N when minimizing quiescent current is critical and load drive requirements are ≤8 mA; avoid for industrial bus interfacing. |
Compared with SN74AC00N, MC74AC00N delivers identical functional behavior and pinout but differs in thermal resistance and manufacturer-specific reliability testing; versus 74VHC00N, MC74AC00N trades higher ICC for significantly stronger output drive and broader supply tolerance - making it preferable for mixed-voltage industrial control.

FAQ
What is the maximum operating supply voltage for MC74AC00N?
The absolute maximum DC supply voltage for MC74AC00N is +6.5 V, but the recommended operating range is 2.0 V to 6.0 V. Operation at 6.0 V is fully characterized for timing, drive strength, and input thresholds per the datasheet's Recommended Operating Conditions table. Exceeding 6.5 V risks permanent damage per the Maximum Ratings specification.
Does MC74AC00N support 3.3 V logic inputs when powered at 5 V?
Yes, MC74AC00N supports 3.3 V logic inputs when VCC = 5 V. Its VIH(min) is 3.15 V at 4.5 V VCC and 3.85 V at 5.5 V VCC, so a 3.3 V high-level input falls within the guaranteed recognition window at 5.0 V supply. This makes MC74AC00N suitable for bridging 3.3 V MCU outputs to 5 V subsystems without level shifters.
Can MC74AC00N drive a standard 74LS TTL input directly?
Yes, MC74AC00N can directly drive a standard 74LS TTL input. With its guaranteed IOH = −24 mA and VOH ≥ 4.4 V at VCC = 5.5 V, it exceeds the 74LS requirement of VOH ≥ 2.7 V and IOH ≥ −0.4 mA. Its IOL = 24 mA also satisfies the 74LS IIH = 20 µA and IIL = −1.6 mA loading requirements with substantial margin.
Is MC74AC00N pin-compatible with MC74ACT00N?
Yes, MC74AC00N and MC74ACT00N share identical pinouts, package dimensions, and logic function. However, they differ in input threshold compatibility: MC74ACT00N is TTL-input compatible (VIH = 2.0 V min), while MC74AC00N requires CMOS-level inputs (VIH scales with VCC). Both operate at 4.5–5.5 V, but MC74AC00N extends down to 2.0 V.
What is the thermal resistance (θJA) of MC74AC00N in SOIC-14 package?
The junction-to-ambient thermal resistance (θJA) for MC74AC00N in the SOIC-14 package (Case 751A) is 116 °C/W, as specified in the Maximum Ratings table. This value assumes standard JEDEC test conditions (JESD51-7) on a 1-inch² copper pad with 2 oz copper and no airflow. Actual board layout will affect real-world thermal performance.
