Product details
Overview
MC74ACT00ML1 from onsemi is a quad 2-input NAND gate IC with TTL-compatible inputs, operating at 4.5–5.5 V supply, delivering ±24 mA output drive, and featuring 4.0 ns typical propagation delay (tPHL/tPLH) at 5 V/50 pF. It is used in digital logic interfacing, bus buffering, and control signal conditioning in industrial control panels.
For engineers reviewing the MC74ACT00ML1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V-only operation, TTL input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), guaranteed 9.5 ns max propagation delay over –40°C to +85°C, and EIAJ-14 (CASE 965) surface-mount package compatibility.
Technical Context
The MC74ACT00ML1 implements four independent 2-input NAND gates in a single monolithic CMOS structure with buffered TTL-compatible input stages. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) ensure direct interfacing with legacy 5 V TTL logic families without level shifting.
It operates strictly within 4.5–5.5 V VCC, exhibits 30 pF power dissipation capacitance, and maintains guaranteed AC performance (tPLH/tPHL ≤ 9.5 ns) under full temperature range (–40°C to +85°C) with 50 pF load - confirming suitability for deterministic timing-critical combinatorial logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - enables compact implementation of basic Boolean logic, reset generation, and enable/disable control in multi-channel systems. |
| Supply Voltage Range | 4.5 V to 5.5 V - restricts use to stable 5 V systems; not compatible with 3.3 V or mixed-voltage domains without translation. |
| Output Drive | ±24 mA per output - supports direct driving of multiple 74-series TTL inputs or small LED indicators without external buffers. |
| Propagation Delay | Max 9.5 ns at 5 V/50 pF over –40°C to +85°C - ensures predictable setup/hold timing in synchronous control logic with ≤100 MHz clock domain edges. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of standard TTL output levels (VOH ≥ 2.4 V, VOL ≤ 0.4 V) without ambiguity. |
| Power Dissipation Cap. | 30 pF - enables accurate dynamic power estimation (P = CPD × VCC² × f) for thermal budgeting in dense PCB layouts. |
Pinout & Package
EIAJ-14 (CASE 965) surface-mount package - 14-pin, 0.3-inch body width, 0.025-inch lead pitch, gull-wing leads; RoHS-compliant, moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | NAND Input A/B | Dedicated logic inputs per gate; TTL-compatible thresholds allow direct connection to 74LS/74F outputs without pull-ups or clamps. |
| 3, 6, 10, 11 | NAND Output Y | CMOS push-pull outputs; ±24 mA drive supports fan-out of ≥10 74LS loads or termination into 50 Ω transmission lines. |
| 7 | GND | Ground reference for all I/O and internal circuitry; requires low-inductance local decoupling (e.g., 100 nF X7R ceramic). |
| 14 | VCC | Positive supply input; must be stabilized within 4.5–5.5 V; noise rejection improved by adjacent 10 µF bulk + 100 nF high-frequency capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V - eliminates need for external level shifters when interfacing with legacy 74LS, 74F, or microcontroller GPIOs. |
| High-Speed Performance | 9.5 ns max propagation delay across full temperature range - enables use in 100+ MHz edge-rate applications such as address decoding and state-machine control. |
| Low Quiescent Current | Max 40 µA ICC at VCC = 5.5 V - reduces static power in always-on subsystems like watchdog timers or power-on reset sequencers. |
| Robust Output Drive | ±24 mA per output - allows direct driving of LEDs (with series resistor), optocouplers, or small relays without discrete transistor stages. |
Applications
| Industrial PLC I/O Conditioning | Legacy System Bus Interface |
|---|---|
Use Scenario: Isolating and conditioning discrete sensor inputs (e.g., limit switches, photoelectric sensors) before feeding into a 5 V microcontroller-based PLC CPU module. IC Role / Device Role / Timing Role: Logic-level translation and noise-immune signal inversion/gating; provides clean, slew-controlled NAND output for interrupt request generation. Use Value: TTL-compatible inputs reject common-mode noise up to ±0.5 V; ±24 mA drive ensures reliable triggering of Schmitt-trigger inputs downstream. | Use Scenario: Interfacing between older 74LS-based backplane bus controllers and newer 5 V FPGA-based peripheral cards requiring standardized enable signals. IC Role / Device Role / Timing Role: Bus arbitration logic element - generating chip-select negation, write strobe inversion, or address decode gating with sub-10 ns timing predictability. Use Value: Guaranteed 9.5 ns max delay ensures setup time compliance for 20 ns cycle-time bus protocols without added wait states. |
| Microcontroller Peripheral Enable Logic | LED Status Indicator Driver |
Use Scenario: Generating active-low enable signals for multiple SPI peripherals (e.g., ADCs, DACs, EEPROMs) from a shared microcontroller GPIO port. IC Role / Device Role / Timing Role: Combinatorial enable decoder - combining address bits and chip-select to produce synchronized peripheral enables with minimal skew. Use Value: Matched propagation delays across all four gates (<0.5 ns skew) prevent race conditions during simultaneous peripheral activation. | Use Scenario: Driving dual-color (red/green) status LEDs on industrial HMI panels where each color indicates system mode (e.g., RUN/FAULT). IC Role / Device Role / Timing Role: Direct-current sink/source driver - using open-drain-like behavior via NAND logic inversion to control LED anode/cathode switching. Use Value: ±24 mA output capability allows 5 mA–15 mA LED current with simple series resistors; eliminates need for external MOSFET drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT00DR | Same logic function, identical 4.5–5.5 V VCC range and TTL-compatible inputs; SOIC-14 (D suffix) package instead of EIAJ-14 (M suffix). | SOIC-14 has wider 1.27 mm lead pitch vs. EIAJ-14's 0.65 mm; requires different stencil aperture and reflow profile. | Select SN74ACT00DR only if board layout uses SOIC footprints and manual rework accessibility is prioritized. |
| 74VHC00M | Higher VCC range (2–5.5 V); CMOS inputs (VIH = 70% VCC) - incompatible with TTL output levels below 3.5 V; 7.5 ns max tPD at 5 V. | Not suitable for direct replacement in legacy TTL systems due to input threshold mismatch; requires redesign of upstream drivers. | Choose 74VHC00M only in new 3.3/5 V mixed-signal designs where input voltage scaling is controlled and lower static power (max 2 µA ICC) is critical. |
Compared with SN74ACT00DR and 74VHC00M, the MC74ACT00ML1 offers guaranteed EIAJ-14 footprint compatibility and native TTL input robustness - making it the preferred choice for drop-in upgrades in space-constrained industrial control modules originally designed for Japanese-market logic ICs.

FAQ
What logic family does the MC74ACT00ML1 belong to, and how does it differ from standard 74AC devices?
The MC74ACT00ML1 belongs to the 74ACT (Advanced CMOS TTL-compatible) family. Unlike 74AC devices rated for 2.0–6.0 V operation, the MC74ACT00ML1 is specified only for 4.5–5.5 V and features TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). This makes MC74ACT00ML1 interoperable with 74LS and 74F logic without level shifters, whereas 74AC variants require careful voltage alignment.
Is the MC74ACT00ML1 pin-compatible with other 14-pin quad NAND gate packages like SOIC-14 or TSSOP-14?
No - the MC74ACT00ML1 uses the EIAJ-14 (CASE 965) package with 0.65 mm lead pitch and specific land pattern dimensions. While electrically identical to SOIC-14 (e.g., MC74ACT00D) and TSSOP-14 (e.g., MC74ACT00DT) variants, the MC74ACT00ML1 requires a dedicated EIAJ-14 footprint; mechanical substitution is not possible without PCB redesign.
What is the maximum capacitive load the MC74ACT00ML1 can drive while maintaining guaranteed timing performance?
The MC74ACT00ML1's AC specifications (e.g., tPLH/tPHL ≤ 9.5 ns) are guaranteed only at CL = 50 pF. Driving loads >50 pF increases propagation delay nonlinearly and may violate setup/hold margins. For 100 pF loads, measured delay exceeds 13 ns; use local buffering or reduce trace length/load capacitance to maintain timing integrity in the MC74ACT00ML1 design.
Does the MC74ACT00ML1 support mixed-voltage operation, such as interfacing with 3.3 V microcontrollers?
No - the MC74ACT00ML1 requires a 4.5–5.5 V VCC supply and has fixed TTL-compatible input thresholds. Its VIH minimum (2.0 V) is insufficient to reliably recognize 3.3 V logic HIGHs (typically 2.4 V min), and its VIL maximum (0.8 V) risks misinterpreting 3.3 V logic LOWs. Use level translators (e.g., TXB0104) or select 74LVC-family NANDs for 3.3 V system integration with MC74ACT00ML1.
What is the thermal performance limit for continuous operation of the MC74ACT00ML1 in an industrial enclosure?
The MC74ACT00ML1 is rated for ambient operation from –40°C to +85°C. Its maximum junction temperature is 140°C, but sustained operation above +70°C ambient requires derating: at TA = +85°C, total power dissipation must remain ≤ 250 mW (calculated from ICC × VCC + dynamic power). Ensure ≥2 cm² copper pour under the EIAJ-14 package and airflow >0.5 m/s for reliable MC74ACT00ML1 deployment in sealed enclosures.
