Product details
Overview
MC74AC10N from onsemi is a triple 3-input NAND gate in high-performance silicon-gate CMOS technology, operating at supply voltages from 2.0 V to 6.0 V, delivering ±24 mA output drive, with propagation delays as low as 4.0 ns (tPHL/tPLH at VCC = 5.0 V, CL = 50 pF), and designed for logic-level translation and combinatorial control in industrial digital systems.
For engineers reviewing the MC74AC10N datasheet, pinout, applications, or equivalent options, this device supports fast-switching TTL- and CMOS-compatible logic design, requires no level-shifting circuitry across 3.3 V/5 V domains, and serves as a drop-in replacement for legacy 74AC10 variants in space-constrained SOIC-14 layouts.
Technical Context
The MC74AC10N implements three independent 3-input NAND gates using advanced silicon-gate CMOS process, ensuring rail-to-rail output swing and low static current (ICC ≤ 40 µA at VCC = 5.5 V). Its input thresholds scale with VCC - VIH = 2.1 V min at VCC = 3.0 V, 3.15 V min at VCC = 4.5 V - enabling robust noise immunity across voltage ranges.
Each gate exhibits matched tPLH/tPHL propagation characteristics (4.0–6.5 ns typical at 5.0 V), low input capacitance (CIN = 4.5 pF), and dynamic output capability up to ±75 mA peak (IOLD/IOHD), supporting capacitive loads and transient-driven interface buffering without external pull-ups.
Key Specifications

| 5, 6, 13 | Input A, B, C of Gate 2 | Independent 3-input set; electrically isolated from Gate 1; identical AC/DC specs |
| 12 | Output Y2 | Second NAND output; shares same VCC/GND rails but no internal coupling to other gates |

|---|---|
Use Scenario: Adding discrete digital output channels to a programmable logic controller via optocoupler-isolated driver banks. IC Role / Device Role / Timing Role: NAND gate used as active-low enable decoder - three MCU GPIO lines select one of eight output drivers via 3-bit binary encoding. Use Value: Reduces firmware overhead by offloading address decoding to hardware; propagation delay <6.5 ns ensures deterministic response under 10 kHz scan cycles. |
Use Scenario: Controlling power sequencing and reset assertion for multiple peripheral ICs (ADC, DAC, transceiver) on an embedded board. IC Role / Device Role / Timing Role: Triple NAND implements synchronized enable gating - two MCU control bits plus global enable generate three independent peripheral power-on signals. Use Value: Eliminates software-based delay loops; rail-to-rail VOH/VOL guarantees full logic swing into 10 kΩ enable inputs across temperature (−40°C to +85°C). |
| Digital Audio Clock Domain Isolation | Legacy Bus Address Decoding |
Use Scenario: Preventing clock domain crossing glitches between a 48 MHz audio codec clock and a 24 MHz DSP core clock. IC Role / Device Role / Timing Role: NAND gate configured as edge-triggered synchronizer - input sampled on rising edge of slow clock, output asserted only after two consecutive high samples. Use Value: Input hysteresis and low propagation skew (<0.5 ns mismatch between gates) suppress metastability without external flip-flops. |
Use Scenario: Translating 16-bit address bus signals into chip-select lines for memory-mapped peripherals in retro-computing or test equipment. IC Role / Device Role / Timing Role: Three independent NANDs decode upper address bits (A13–A15) to generate CS0–CS2 for SRAM, EPROM, and I/O port chips. Use Value: Guaranteed setup/hold timing margins at 5 V allow reliable operation up to 8 MHz bus speeds without added wait states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC10N | Same logic function, pinout, and AC/DC specs; TI-manufactured with identical SOIC-14 footprint and 2.0–6.0 V operation | No functional deviation - validated for drop-in use in existing MC74AC10N layouts | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation |
| 74VHC10N | Higher speed (tPD = 3.5 ns typ @ 5 V), lower ICC (2 µA max), but VIH/VIL thresholds fixed at 3.5 V/1.5 V - not VCC-scaled | Requires stable 5 V supply; unsuitable for 3.3 V-only systems without level translation | Prefer for high-frequency timing-critical paths where supply is strictly 5 V and leakage must be minimized |
Compared with SN74AC10N, MC74AC10N offers identical electrical behavior and layout compatibility, while 74VHC10N trades supply flexibility for marginal speed gain and lower quiescent current - making MC74AC10N optimal for mixed-voltage industrial control where reliability and voltage adaptability outweigh nanosecond-level timing gains.

FAQ
What is the maximum operating frequency supported by the MC74AC10N?
The MC74AC10N does not specify a maximum clock frequency because it is a combinational logic device without internal clocking. Its usable toggle rate depends on propagation delay and load capacitance: with CL = 50 pF and VCC = 5.0 V, tPHL/tPLH is 4.0–6.5 ns, enabling reliable operation in logic paths up to approximately 100 MHz for simple gate chains. For precise timing analysis, designers must calculate worst-case path delay including trace capacitance and fanout.
Can the MC74AC10N operate at 3.3 V and interface directly with 5 V TTL devices?
Yes, the MC74AC10N operates over 2.0–6.0 V and features CMOS inputs with VIL = 0.9 V max and VIH = 2.1 V min at VCC = 3.0 V - well within TTL output voltage ranges (0.4 V low, 2.4 V high). Its outputs swing rail-to-rail, producing VOH ≈ 3.3 V and VOL ≈ 0 V at 3.3 V supply, which are recognized as valid HIGH/LOW by 5 V TTL inputs. No level-shifter is needed for bidirectional interfacing.
Is the MC74AC10N pin-compatible with the MC74ACT10?
No, the MC74AC10N and MC74ACT10 are not pin-compatible. While both are triple 3-input NANDs in SOIC-14 packages, the MC74ACT10 has TTL-compatible inputs (VIH = 2.0 V fixed, not VCC-scaled), resulting in different DC input thresholds and slightly modified AC behavior. They share identical pinouts and package dimensions, but substituting one for the other may cause logic errors if input voltage levels fall outside the respective VIH/VIL windows.
What is the thermal resistance (θJA) of the MC74AC10N in SOIC-14 package?
The MC74AC10N in SOIC-14 package (Case 751A) has a junction-to-ambient thermal resistance (θJA) of 116°C/W, as specified in the Maximum Ratings table. This value assumes standard JEDEC test conditions (single-layer board, 1 in² copper pad). Actual θJA in end-user PCBs will vary based on copper area, airflow, and adjacent heat sources - derating is recommended above 70°C ambient for continuous 50 mW dissipation.
Does the MC74AC10N require external pull-up or pull-down resistors on unused inputs?
Yes, all unused inputs of the MC74AC10N must be terminated to a defined logic level - either VCC or GND - using external resistors (typically 1–10 kΩ). Floating CMOS inputs can drift into the linear region, causing excessive supply current, oscillation, or increased EMI susceptibility. Leaving inputs unconnected violates the Absolute Maximum Ratings for input voltage and risks latch-up or premature device failure.
