Product details
Overview
MC74AC10DR2 from onsemi is a triple 3-input NAND gate in high-performance silicon-gate CMOS technology, operating at 2.0–6.0 V supply, delivering ±24 mA output drive, with propagation delays as low as 4.0 ns (tPHL/tPLH @ 5.0 V, CL = 50 pF), and designed for logic-level translation and combinatorial control in industrial digital systems.
For engineers reviewing the MC74AC10DR2 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 package details, functional role in NAND-based decoding and enable gating, and validated alternative options for 3-input CMOS logic replacement.
Technical Context
The MC74AC10DR2 implements three independent 3-input NAND gates in a single SOIC-14 package, with CMOS input thresholds (VIH = 2.1 V min @ VCC = 3.0 V; VIL = 0.9 V max) and rail-to-rail output swing. It supports operation across −40°C to +85°C ambient temperature and exhibits low dynamic power dissipation (CPD = 25 pF @ VCC = 5.0 V).
Its AC performance is characterized at CL = 50 pF, with guaranteed tPHL/tPLH ≤ 8.0 ns (max) at VCC = 5.0 V and ≤ 10.5 ns (max) at VCC = 3.3 V. Input leakage remains ≤ ±1.0 µA, and it meets JEDEC JESD78 latch-up immunity (>100 mA) and ESD robustness (>2000 V HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Three independent 3-input NAND gates - enables compact implementation of AND-NOT logic trees without external inversion. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V logic driving 5 V loads via level-shifting design). |
| Output Drive | ±24 mA - sufficient to directly drive TTL inputs or small capacitive loads (< 50 pF) without buffering. |
| Propagation Delay | ≤ 8.0 ns max @ 5.0 V, CL = 50 pF - ensures timing-critical combinational paths meet sub-10 ns budget in synchronous control logic. |
| Input Thresholds | VIH = 2.1 V min / VIL = 0.9 V max @ 3.0 V - provides >1.2 V noise margin against ground bounce in noisy industrial PCB environments. |
| Power Dissipation Cap | 1077 mW @ TA = 25°C (SOIC) - allows sustained operation under moderate fanout without thermal derating in enclosed enclosures. |
Pinout & Package
MC74AC10DR2 is housed in a Pb-free SOIC-14 (Case 751A) package, 8.75 mm × 3.90 mm × 1.75 mm, with standard 1.27 mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Gate 1 Inputs | Three logic inputs to first NAND gate - all must be HIGH for output (Pin 4) to go LOW. |
| 4 | Gate 1 Output | Inverted AND result of Pins 1–3 - active-low logic output compatible with enable/disable control signals. |
| 5, 6, 13 | Gate 2 Inputs | Three logic inputs to second NAND gate - electrically isolated from Gate 1; shares no internal nodes. |
| 12 | Gate 2 Output | Independent inverted AND output - usable for parallel decode or redundant logic verification paths. |
| 8, 9, 10 | Gate 3 Inputs | Three logic inputs to third NAND gate - supports triple-function logic partitioning on one IC. |
| 11 | Gate 3 Output | Dedicated output for third function - eliminates need for discrete gate duplication in state-machine glue logic. |
| 7 | GND | Ground reference for all gates - must be low-impedance connection to minimize switching noise coupling. |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed CMOS | Sub-10 ns propagation delay at 5 V enables use in 50+ MHz clock-domain control logic. |
| Pb-Free Construction | RoHS-compliant SOIC-14 package (suffix "G") - meets IPC-J-STD-020 moisture sensitivity Level 1. |
| Rail-to-Rail Output Swing | VOH ≥ 4.4 V / VOL ≤ 0.44 V @ IOL/IOH = ±24 mA - ensures full logic-level compatibility with 5 V TTL and CMOS families. |
| Wide Supply Range | Operates from 2.0 V to 6.0 V - supports battery-backed 3.3 V systems and legacy 5 V industrial controllers. |
| Low Input Leakage | IIN ≤ ±1.0 µA over temperature - prevents unintended pull-up/pull-down in high-impedance bus or sensor interface applications. |
Applications
| Industrial PLC I/O Expansion | Automated Test Equipment (ATE) Signal Gating |

IC Role / Device Role / Timing Role: MC74AC10DR2 performs hardware-level AND-NOT validation of two MCU WDT signals plus a manual reset input. Use Value: Guaranteed latch-up immunity (>100 mA) and −40°C to +85°C operation ensure fail-safe behavior across clinical environmental ranges. |
Use Scenario: Aggregating fault flags from 12 proximity sensors into a single "system OK" status line using wired-OR with pull-up and NAND inversion. IC Role / Device Role / Timing Role: MC74AC10DR2 implements distributed NAND-based fault aggregation across three sensor groups (4 sensors each). Use Value: Low 25 pF power-dissipation capacitance minimizes dynamic current draw in always-on sensor monitoring circuits, extending uptime in battery-buffered hubs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input NAND logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC10N | Same logic function, identical AC/DC specs, but offered in PDIP-14 (through-hole) instead of SOIC-14 surface-mount. | Requires through-hole PCB assembly; unsuitable for high-density automated SMT lines. | Select SN74AC10N only for prototyping, repair, or legacy through-hole designs where rework tolerance outweighs density constraints. |
| MC74ACT10DR2G | TTL-compatible inputs (VIH/VIL fixed at 2.0 V/0.8 V), otherwise identical pinout, speed, and drive strength. | Better interoperability with legacy 5 V TTL outputs; less suitable for mixed 3.3 V/5 V voltage translation due to tighter input thresholds. | Choose MC74ACT10DR2G when interfacing directly with 74LS or 74F series outputs; retain MC74AC10DR2 for flexible multi-supply logic level adaptation. |
Compared with SN74AC10N and MC74ACT10DR2G, the MC74AC10DR2 offers optimal surface-mount integration and wide-voltage input compatibility - making it preferred for new industrial control designs requiring both density and supply flexibility.

FAQ
What is the maximum operating supply voltage for MC74AC10DR2?
The MC74AC10DR2 supports a DC supply voltage range of 2.0 V to 6.0 V, with absolute maximum rating at +6.5 V. Operation above 6.0 V is not recommended, as parametric performance is only guaranteed up to 6.0 V per the datasheet's Recommended Operating Conditions table. Exceeding this may compromise timing margins or increase ICC beyond specification.
Does MC74AC10DR2 have TTL-compatible inputs?
No, MC74AC10DR2 does not have TTL-compatible inputs. Its input thresholds scale with VCC (e.g., VIH = 2.1 V min @ 3.0 V), unlike the fixed 2.0 V/0.8 V thresholds of the TTL-compatible MC74ACT10DR2G. This makes MC74AC10DR2 better suited for mixed-supply systems but less ideal for direct interfacing with legacy 5 V TTL outputs without level shifting.
What is the pinout configuration of MC74AC10DR2 in SOIC-14?
The MC74AC10DR2 uses standard SOIC-14 pinout: Pins 1–3 and 4 = Gate 1 (3 inputs + output); Pins 5,6,13 and 12 = Gate 2; Pins 8–10 and 11 = Gate 3; Pin 7 = GND; Pin 14 = VCC. This matches Figure 1 in the official datasheet and is identical across all 74AC10 variants in SOIC-14 packaging.
Is MC74AC10DR2 suitable for automotive applications?
MC74AC10DR2 is not qualified to AEC-Q100 standards and is specified only for industrial temperature range (−40°C to +85°C). While its operating range overlaps with some automotive cabin applications, it lacks automotive-grade qualification, stress testing, and PPAP documentation - so it should not be used in safety-critical or engine-compartment automotive systems without additional validation.
What is the typical power dissipation of MC74AC10DR2 at 5 V operation?
At VCC = 5.0 V and TA = 25°C, the MC74AC10DR2 exhibits a typical power dissipation capacitance (CPD) of 25 pF. With dynamic switching, total power scales as P = CPD × VCC² × f, enabling accurate estimation - e.g., at 10 MHz toggle rate, average dynamic power is ~6.25 mW per gate, well within the 1077 mW SOIC package limit.
