Product details
Overview
74AC10MTR from STMicroelectronics is a triple 3-input NAND gate IC in TSSOP-14 package, operating at 2–6 V supply, delivering 4 ns typical propagation delay (at 5 V), ±24 mA symmetrical output drive, and 2 µA max quiescent current at 25°C. It serves as a high-speed combinational logic element in digital control, address decoding, and bus interface circuits.
For engineers reviewing the 74AC10MTR datasheet, 74AC10MTR pinout, 74AC10MTR application, or 74AC10MTR equivalent, key selection criteria include transmission-line driving capability (50 Ω), latch-up immunity, ESD tolerance (2 kV), noise margin (28% VCC), and compatibility with legacy 74-series logic families.
Technical Context
The 74AC10MTR implements three independent 3-input NAND gates using sub-micron C2MOS technology with buffered outputs, enabling stable switching and high noise immunity. Its symmetrical output impedance (|IOH| = IOL ≥ 24 mA) and balanced tPLH/tPHL delays support clean signal integrity in mixed-slew-rate environments.
Input thresholds are specified across temperature and voltage (e.g., VIH = 3.15 V min at VCC = 4.5 V), and it meets 50 Ω transmission-line driving requirements per gate with CL = 50 pF and RL = 500 Ω test conditions. Absolute maximum ratings include VCC up to +7 V and storage temperature from −65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| tPD (Typ) | 4 ns at VCC = 5 V - enables >100 MHz toggle rates in critical timing paths |
| IOL / IOH | ≥24 mA - drives standard 50 Ω transmission lines without external termination |
| VNIH / VNIL | 28% VCC min - provides robust noise rejection in electrically noisy industrial environments |
| ICC (Max) | 2 µA at TA = 25°C - ultra-low static power for always-on logic monitoring functions |
| ESD Rating | 2 kV HBM - protects against handling-induced discharge without external clamping |
| Operating Temp | −55 °C to +125 °C - qualified for extended-temperature automotive and industrial control |

| 13, 5, 11 | 1C, 2C, 3C | Third input of each NAND gate - referenced to same VCC/GND rails for rail-to-rail swing |
| 12, 6, 8 | 1Y, 2Y, 3Y | Active-low NAND outputs - capable of sourcing/sinking ≥24 mA with matched rise/fall times |

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 |
|---|---|---|---|
| SN74AC10DR | Same logic function, SOIC-14 package, identical AC/DC specs, but lower ESD rating (1.5 kV HBM) | Preferred where board space allows SOIC and cost is prioritized over ruggedness | Select when footprint compatibility with legacy SOIC layouts is required and ESD stress is controlled |
| 74LVC10PW | Lower VCC range (1.65–5.5 V), higher speed (tPD = 3.2 ns typ), but reduced drive (±24 mA only at VCC ≥ 4.5 V) | Better suited for 3.3 V-only systems with tighter timing budgets | Choose for new 3.3 V designs requiring faster propagation and lower dynamic power |
Compared with SN74AC10DR and 74LVC10PW, the 74AC10MTR offers superior ESD robustness and guaranteed 50 Ω line driving across its full 2–6 V range - making it optimal for industrial and automotive applications demanding field reliability and mixed-voltage interoperability.

FAQ
Is the 74AC10MTR pin-compatible with standard 74LS10 or 74HC10 devices?
Yes - the 74AC10MTR uses identical pinout and truth table as 74-series triple 3-input NAND gates including 74LS10 and 74HC10. However, its input thresholds (VIH/VIL) and output drive strength differ: it requires no pull-ups for TTL-level inputs and delivers ±24 mA versus ±8 mA for LS and ±5.2 mA for HC, enabling direct replacement with improved performance.
What is the maximum recommended capacitive load for reliable 4 ns propagation delay?
The 4 ns typical tPD is specified with CL = 50 pF and RL = 500 Ω. For loads exceeding 50 pF, propagation delay increases linearly - e.g., at CL = 100 pF, tPD degrades to ~6.5 ns. To maintain timing integrity, keep total node capacitance ≤50 pF or add series termination to limit ringing.
Does the 74AC10MTR support mixed-voltage operation between inputs and outputs?
No - all inputs and outputs share a single VCC rail; the device does not support dual-supply or level-shifting operation. Input voltage must stay within 0 to VCC, and output swing is rail-to-rail relative to that same VCC. For mixed-voltage interfacing, external level translators are required.
Can the 74AC10MTR drive multiple 74AC-series inputs directly?
Yes - with fanout of ≥10 into other 74AC inputs (each drawing ≤1 µA IIH/IIL), the 74AC10MTR can drive up to 10 downstream gates without degradation. Fanout drops to ~4 when driving 74LS inputs due to their higher input current (−0.4 mA), requiring buffer stages in mixed-family designs.
