Product details
Overview
74ACT10MTCX from Fairchild Semiconductor is a triple 3-input NAND gate logic IC designed for high-speed, TTL-compatible digital signal processing in industrial control and embedded interface circuits. It operates at 4.5V–5.5V supply, delivers ±24mA output drive, achieves 6.5ns typical propagation delay (tPLH/tPHL), and supports –40°C to +85°C industrial temperature range. It is used in address decoding, bus gating, and enable logic for microcontroller peripheral interfaces.
For engineers reviewing the 74ACT10MTCX datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, TSSOP-14 package details, real-world timing and drive capability data, and validated alternative options for logic-level compatibility and supply voltage matching.
Technical Context
The 74ACT10MTCX implements three independent 3-input NAND gates using advanced ACT (Advanced CMOS with TTL-compatible inputs) process technology. Its input thresholds (VIH = 2.0V min, VIL = 0.8V max at VCC = 4.5V) ensure robust interfacing with standard TTL and 5V CMOS logic families.
Each gate features rail-to-rail output swing (VOH ≥ 4.4V, VOL ≤ 0.44V at IOL/IOH = ±24mA), low dynamic power dissipation (CPD = 25pF), and fast edge-rate handling (minimum ∆V/∆t = 125mV/ns). No internal pull-ups, latches, or enable controls are present - it is a pure combinational logic device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Three independent 3-input NAND gates - no shared control lines or internal feedback |
| Supply Voltage Range | 4.5V to 5.5V - requires regulated 5V rail; not compatible with 3.3V-only systems |
| Propagation Delay | 6.5ns typical (tPLH/tPHL, VCC = 5.0V, CL = 50pF) - enables <150MHz toggle rate in clean load conditions |
| Output Drive | ±24mA per output - sufficient to directly drive LED indicators, small MOSFET gates, or multiple 74-series inputs |
| Input Thresholds | VIH ≥ 2.0V, VIL ≤ 0.8V (VCC = 4.5V) - ensures reliable recognition of TTL-level signals without level shifters |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade PCB deployment without derating |
| Power Dissipation Cap | CPD = 25pF - allows accurate dynamic power estimation (P = CPD × VCC² × f) for thermal design |
Pinout & Package
74ACT10MTCX is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with 0.65mm lead pitch. The package is lead-free and RoHS-compliant per J-STD-020B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13 | Input A1, B1, C1 | First NAND gate inputs - all three must be HIGH for Output 1 (pin 3) to go LOW |
| 3 | Output O1 | Inverted AND of pins 1, 2, 13 - active-low logic output with full 5V rail swing |
| 4, 5, 6 | Input A2, B2, C2 | Second NAND gate inputs - electrically isolated from Gate 1 |
| 8 | Output O2 | Inverted AND of pins 4, 5, 6 - shares no internal nodes with other gates |
| 9, 10, 11 | Input A3, B3, C3 | Third NAND gate inputs - fully independent signal path |
| 12 | Output O3 | Inverted AND of pins 9, 10, 11 - supports simultaneous switching with O1/O2 |
| 7 | GND | Dedicated ground reference for all three gates - must be low-impedance connection |
| 14 | VCC | Single positive supply for entire IC - decoupling capacitor (0.1µF) required at pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Accepts standard 0.8V/2.0V logic thresholds - eliminates need for external level translators when interfacing with legacy 74LS or microcontroller GPIO |
| High-output current drive | ±24mA per output - enables direct fanout to up to 10 74ACT inputs or driving small-signal discrete loads without buffers |
| Low quiescent ICC | Max 40µA at VCC = 5.5V - reduces static power in always-on control logic sections |
| Fast propagation delay | 6.5ns typical (5V, 50pF) - supports synchronous timing margins down to ~15ns in critical path logic |
| Industrial temperature range | –40°C to +85°C operation - validated across full range with no parameter derating required |
Applications
| Industrial PLC Input Conditioning | Microcontroller Bus Enable Logic |
|---|---|
Use Scenario: Isolating and validating field sensor inputs before feeding into a programmable logic controller's digital input module. IC Role / Device Role / Timing Role: 74ACT10MTCX acts as a 3-input validation gate - only when three safety interlocks (e.g., door closed, guard engaged, reset pressed) are asserted does it enable the input latch strobe. Use Value: Ensures hardware-level AND logic precedence over firmware - prevents unsafe state transitions even during MCU lockup or boot-up. |
Use Scenario: Controlling access to an 8-bit parallel data bus shared between an MCU and multiple peripherals (ADC, DAC, display driver). IC Role / Device Role / Timing Role: 74ACT10MTCX generates chip-select enable signals by combining address bits and master enable - each gate drives one peripheral's /CS line. Use Value: Provides deterministic, zero-latency bus arbitration without software overhead or interrupt latency dependency. |
| Legacy System TTL Interface Bridge | Power Sequencing Control Logic |
Use Scenario: Interfacing modern 5V CMOS microcontrollers with older TTL-based instrumentation subsystems (e.g., GPIB controllers, test equipment backplanes). IC Role / Device Role / Timing Role: 74ACT10MTCX serves as bidirectional logic-level translator - its TTL-compatible inputs accept 0.8V/2.0V thresholds while driving full 5V CMOS outputs. Use Value: Eliminates need for discrete resistor networks or dedicated level-shifter ICs in mixed-technology system integration. |
Use Scenario: Enabling power rails in strict sequence (e.g., 12V → 5V → 3.3V) for FPGA or DSP subsystems with multiple voltage domains. IC Role / Device Role / Timing Role: 74ACT10MTCX implements "AND-of-ready" logic - only when all upstream regulators report OK (via open-drain READY signals) does it assert the next-stage enable. Use Value: Guarantees hardware-enforced sequencing compliance - prevents latch-up or damage due to reverse bias on IC power pins. |
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 |
|---|---|---|---|
| SN74ACT10DR | Same logic function, identical AC/ACT electrical specs, SOIC-14 package (M14A) instead of TSSOP-14 | Requires PCB layout change - 3.9mm wider body, 1.27mm lead pitch vs. 0.65mm | Select when board space permits larger footprint and hand-soldering or legacy reflow profiles are used. |
| 74LCX10MTCX | Lower VCC range (2.0–3.6V), LVTTL-compatible inputs, 5.5ns typical delay, same TSSOP-14 package | Not 5V-tolerant; cannot replace 74ACT10MTCX in 5V systems without level shifting | Select only for new 3.3V designs where lower static power (ICC < 10µA) and reduced EMI are prioritized. |
Compared with SN74ACT10DR and 74LCX10MTCX, the 74ACT10MTCX uniquely balances 5V TTL interoperability, TSSOP-14 compactness, and industrial temperature support - making it the only choice for space-constrained 5V industrial control boards requiring guaranteed noise-immune input thresholds.

FAQ
What is the maximum operating supply voltage for the 74ACT10MTCX?
The 74ACT10MTCX has an absolute maximum VCC rating of +7.0V, but its recommended operating range is strictly 4.5V to 5.5V per datasheet Rev. 1.7.1. Operating outside this window - especially below 4.5V - risks VIH/VIL threshold violation and unreliable logic transitions. The 74ACT10MTCX must be powered from a well-regulated 5V source.
Does the 74ACT10MTCX support 3.3V logic inputs?
No, the 74ACT10MTCX does not reliably recognize 3.3V logic levels as HIGH. Its minimum VIH is 2.0V at VCC = 4.5V, but 3.3V systems typically produce VOH ≈ 3.3V - which exceeds the 74ACT10MTCX's input threshold. However, the 74ACT10MTCX itself cannot be powered from 3.3V; it requires 4.5–5.5V. So 3.3V-to-5V translation is mandatory for safe interfacing with the 74ACT10MTCX.
What is the pinout compatibility between 74ACT10MTCX and 74AC10MTCX?
The 74ACT10MTCX and 74AC10MTCX share identical pinouts and package (TSSOP-14), but differ electrically: 74AC10MTCX operates from 2.0–6.0V and has looser input thresholds (VIH = 3.15V min at 4.5V), while 74ACT10MTCX mandates 4.5–5.5V and tighter TTL-compatible thresholds (VIH = 2.0V min). They are pin-compatible but not functionally interchangeable without verifying supply and signal level alignment.
Can the 74ACT10MTCX drive an LED directly?
Yes - the 74ACT10MTCX can sink up to 24mA per output, sufficient to drive standard 2mA–20mA indicator LEDs. For a typical red LED (VF ≈ 1.8V), use a series resistor of ~130Ω when VCC = 5V (R = (5V − 1.8V)/24mA). Ensure total ICC remains within 50mA per supply pin and thermal limits are observed under continuous drive.
Is the 74ACT10MTCX RoHS-compliant and lead-free?
Yes - the 74ACT10MTCX is manufactured per JEDEC J-STD-020B and marked as lead-free. Its TSSOP package uses matte tin lead finish, and the device complies with RoHS Directive 2011/65/EU. This is explicitly confirmed in the "Ordering Information" section of the Fairchild datasheet Rev. 1.7.1, which states "All packages are lead free per JEDEC: J-STD-020B standard."
