Product details
Overview
MC74AC00MR1 from onsemi is a quad 2-input NAND gate logic IC in EIAJ-14 (SOIC-14) package, operating at 2.0–6.0 V supply, delivering ±24 mA output drive, with propagation delays as low as 1.5 ns at 5.0 V, and used in digital control, address decoding, and bus interface circuits.
For engineers reviewing the MC74AC00MR1 datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2.0–6.0 V), output drive strength (±24 mA), AC timing at 50 pF load, input compatibility (CMOS-level thresholds), and EIAJ-14 thermal and mounting characteristics.
Technical Context
The MC74AC00MR1 implements four independent 2-input NAND gates using advanced CMOS technology, supporting rail-to-rail input voltage operation from –0.5 V to VCC + 0.5 V and output swing within the same range. It features TTL-compatible input thresholds only in the ′ACT variant - this ′AC version uses standard CMOS input levels (VIH = 2.1 V min at VCC = 3.0 V).
Its AC performance is specified at CL = 50 pF, with tPLH/tPHL as low as 1.5 ns (typ) at VCC = 5.0 V, and DC output capability rated for ±24 mA per pin under guaranteed conditions. Quiescent ICC remains ≤4.0 µA across –40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - enables basic combinational logic, enable/disable control, and signal inversion in digital systems. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered 3.3 V/5.0 V designs. |
| Output Drive | ±24 mA per output - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74AC inputs without buffering. |
| Propagation Delay | 1.5 ns (typ), 8.5 ns (max) at VCC = 5.0 V, CL = 50 pF - enables reliable operation in sub-100 MHz synchronous logic paths. |
| Input Thresholds | VIH = 2.1 V min, VIL = 0.9 V max at VCC = 3.0 V - ensures noise margin >0.6 V in 3.3 V systems with standard CMOS signaling. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control, instrumentation, and communications equipment. |
| Power Dissipation Cap | CPD = 30 pF - allows accurate dynamic power estimation (P = CPD × VCC² × f) for thermal design at high toggle rates. |
Pinout & Package
EIAJ-14 (SOIC-14) package, 3.9 mm width, 1.27 mm pitch, gull-wing leads, JEDEC MS-012 compliant, suitable for reflow soldering and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input A/B of NAND gates | Dual inputs per gate; all inputs are CMOS-compatible with high impedance (>10⁹ Ω) and low leakage (±1.0 µA max). |
| 3, 6, 10, 13 | NAND Output | Push-pull CMOS outputs capable of sourcing/sinking ±24 mA while maintaining VOH ≥2.9 V / VOL ≤0.44 V at VCC = 3.0–5.5 V. |
| 7 | GND | Ground reference for all I/O and internal circuitry; requires low-impedance PCB connection to minimize ground bounce. |
| 14 | VCC | Positive supply rail; bypass capacitor (0.1 µF ceramic) recommended within 5 mm of pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed AC Performance | 1.5 ns typical propagation delay at 5.0 V enables use in fast clock distribution and pipeline control logic. |
| Wide Supply Range | 2.0–6.0 V operation allows direct integration into both 3.3 V microcontroller peripherals and legacy 5 V bus systems. |
| Low Dynamic Power | 30 pF power dissipation capacitance supports efficient high-frequency operation with predictable power scaling. |
| Robust Input Protection | Rated for ±20 mA DC input current and –0.5 V to VCC + 0.5 V input voltage - withstands transient overvoltage and hot-swap stress. |
| Industrial Temp Grade | –40°C to +85°C guaranteed operation ensures reliability in uncontrolled environments like factory automation panels. |
Applications

IC Role / Device Role / Timing Role: Noise-immune gating of trigger and strobe signals before FPGA capture. Use Value: Input hysteresis not present, but VIH/VIL margins >0.6 V suppress false triggering from 50–100 mV noise peaks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC00N | Same logic function, identical AC/DC specs, PDIP-14 package (larger footprint, higher thermal resistance). | Preferred for prototyping or through-hole assembly; unsuitable for high-density SMT layouts. | Select SN74AC00N when manual soldering or breadboard evaluation is required. |
| MC74AC00DR2 | Identical electrical specs and EIAJ-14 footprint, but supplied in 2500-unit tape-and-reel format (vs. MC74AC00MR1's rail packaging). | Optimized for automated pick-and-place production; no functional difference in circuit behavior. | Choose MC74AC00DR2 for high-volume SMT manufacturing with feeder compatibility. |
Compared with SN74AC00N and MC74AC00DR2, the MC74AC00MR1 offers identical logic performance and electrical behavior in the same EIAJ-14 package, differing only in packaging format (rail vs. reel) and manufacturer marking - making it ideal for mid-volume production and engineering sampling where rail delivery simplifies kitting and inventory staging.

FAQ
What is the maximum supply voltage rating for the MC74AC00MR1?
The MC74AC00MR1 has an absolute maximum DC supply voltage (VCC) of +7.0 V referenced to GND. However, functional operation is restricted to the recommended range of 2.0 V to 6.0 V. Operating continuously above 6.0 V risks parametric degradation or permanent damage, even if within the absolute maximum rating.
Does the MC74AC00MR1 support TTL-level input signals?
No, the MC74AC00MR1 does not support TTL-level inputs. It is the ′AC variant - its input thresholds follow standard CMOS levels (e.g., VIH = 2.1 V min at VCC = 3.0 V). For TTL-compatible inputs, the ′ACT variant (e.g., MC74ACT00MR1) must be used instead.
What is the output current capability of each NAND gate in the MC74AC00MR1?
Each output of the MC74AC00MR1 can source or sink up to ±24 mA while maintaining guaranteed VOH ≥2.9 V and VOL ≤0.44 V across VCC = 3.0–5.5 V and TA = –40°C to +85°C. This is validated per-output, not total device current.
Can the MC74AC00MR1 operate reliably at 3.3 V supply?
Yes, the MC74AC00MR1 is fully specified at 3.3 V (within its 2.0–6.0 V range), with VIH = 1.5 V min, VIL = 0.9 V max, VOH ≥2.9 V, VOL ≤0.44 V, and tPLH/tPHL ≤9.5 ns at CL = 50 pF - making it suitable for direct interface with 3.3 V microcontrollers and FPGAs.
What package type is used by the MC74AC00MR1?
The MC74AC00MR1 uses the EIAJ-14 package - a 14-pin SOIC variant with 3.9 mm body width and 1.27 mm lead pitch, also known as CASE 965. It is dimensionally and electrically equivalent to JEDEC MS-012 SOIC-14 but marked per EIAJ standards.
