Product details
Overview
74ACT10MTC 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 within 4.5V–5.5V supply range, delivers ±24mA output drive, exhibits 6.5ns typical propagation delay at 5V, and supports –40°C to +85°C industrial temperature operation.
For engineers reviewing the 74ACT10MTC datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, TSSOP-14 package mapping, DC/AC electrical specifications, real-world use context, and validated alternative options for logic-level translation and combinational gating tasks.
Technical Context
The 74ACT10MTC 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 4.5V) ensure robust noise immunity and direct interfacing with standard TTL outputs.
Each gate features rail-to-rail output swing (VOH ≥ 4.4V, VOL ≤ 0.44V at IO = ±24mA), low quiescent ICC (4.0µA typ), and dynamic output current capability (±75mA peak) enabling reliable fanout into multiple CMOS or TTL loads without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Three independent 3-input NAND gates - enables compact implementation of sum-of-products logic and enable/control tree structures. |
| Supply Voltage Range | 4.5V to 5.5V - ensures compatibility with standard 5V TTL and mixed-voltage systems while maintaining noise margin. |
| Propagation Delay | 6.5ns typical (tPLH/tPHL, VCC = 5V, CL = 50pF) - supports >100MHz toggle rates in critical timing paths. |
| Output Drive | ±24mA per output - directly drives up to 10 LSTTL loads or 20 CMOS inputs without level-shifting. |
| Input Thresholds | VIH = 2.0V min, VIL = 0.8V max (at VCC = 4.5V) - guarantees reliable recognition of legacy TTL logic levels. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade reliability in non-automotive embedded environments. |
| Package | TSSOP-14 (JEDEC MO-153, 4.4mm wide) - surface-mount footprint optimized for high-density PCB layouts with thermal and mechanical stability. |
Pinout & Package
74ACT10MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, with 0.65mm lead pitch and 4.4mm body width. The package supports reflow soldering and offers improved thermal dissipation over standard SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13 | Gate 1 Inputs (A1, B1, C1) | Three logic inputs for first NAND gate - all must be HIGH to produce LOW output. |
| 3 | Gate 1 Output (Y1) | Inverted AND result of pins 1,2,13 - active-low logic output with full rail swing. |
| 4, 5, 12 | Gate 2 Inputs (A2, B2, C2) | Three logic inputs for second NAND gate - electrically isolated from Gate 1. |
| 6 | Gate 2 Output (Y2) | Independent inverted AND output - supports parallel logic path implementation. |
| 8, 9, 10 | Gate 3 Inputs (A3, B3, C3) | Three logic inputs for third NAND gate - occupies lower-left quadrant of pinout. |
| 11 | Gate 3 Output (Y3) | Third independent output - enables triple-gate logic functions in single-package footprint. |
| 7 | GND | Ground reference for all internal circuitry and I/O - must be low-impedance connection. |
| 14 | VCC | +5V power supply - decoupling capacitor (0.1µF) required adjacent to pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH/VIL thresholds match standard TTL (2.0V/0.8V @ 4.5V), enabling direct interconnection with 74LS/74F families without level shifters. |
| High-output drive strength | ±24mA sink/source per output supports driving multiple downstream loads or transmission lines with minimal signal degradation. |
| Low propagation delay | 6.5ns typical (5V, 50pF) ensures timing-critical applications like address decoding and clock gating meet tight setup/hold windows. |
| Low quiescent current | 4.0µA typical ICC allows use in power-sensitive industrial controllers where standby consumption matters. |
| Industrial temperature range | –40°C to +85°C operation validated across full voltage range - suitable for factory automation and outdoor equipment. |

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 |
|---|---|---|---|
| SN74ACT10D | SOIC-14 package (M14A), identical AC/ACT electrical specs and pinout - same die, different封装. | No change in logic function or timing; requires PCB layout revision for SOIC vs. TSSOP footprint. | Select SN74ACT10D if board design uses SOIC land pattern or requires higher thermal mass for manual rework. |
| 74LCX10MTCX | Lower VCC range (2.0–3.6V), 3.3V-only compatible; VIH/VIL scaled for LVCMOS, not TTL - not pin-compatible for 5V systems. | Only suitable for 3.3V domains; cannot replace 74ACT10MTC in 5V legacy interfaces without level shifting. | Choose 74LCX10MTCX only when migrating to 3.3V logic families and redesigning power architecture. |
Compared with SN74ACT10D and 74LCX10MTCX, the 74ACT10MTC uniquely balances 5V TTL interoperability, TSSOP space efficiency, and industrial temperature support - making it the optimal choice for retrofitting legacy 5V systems where board area and signal integrity are constrained.

FAQ
What logic family does the 74ACT10MTC belong to, and how does it differ from standard 74AC devices?
The 74ACT10MTC belongs to the Advanced CMOS with TTL-compatible (ACT) logic family. Unlike 74AC variants, which operate from 2.0V–6.0V and have CMOS-level inputs, the 74ACT10MTC features TTL-compatible input thresholds (VIH = 2.0V min, VIL = 0.8V max at 4.5V) and is specified only for 4.5V–5.5V operation - ensuring reliable interfacing with legacy 74LS and 74F devices without level shifters. This makes the 74ACT10MTC distinct in both voltage range and input compatibility compared to generic 74AC parts.
Can the 74ACT10MTC be used in a 3.3V system?
No, the 74ACT10MTC is not rated for 3.3V operation. Its recommended operating VCC range is strictly 4.5V to 5.5V, and its input thresholds are defined only at 4.5V and 5.5V. Using it at 3.3V risks unreliable switching, excessive ICC, or failure to recognize logic HIGH inputs. For 3.3V systems, consider 74LVC10 or 74LCX10 instead - but note these are not pin-compatible replacements for the 74ACT10MTC.
What is the maximum capacitive load the 74ACT10MTC can drive while maintaining specified propagation delay?
The 74ACT10MTC's AC Electrical Characteristics are specified with CL = 50pF, and its typical propagation delay (6.5ns) is guaranteed under that condition. Driving loads significantly above 50pF increases delay nonlinearly and may degrade edge rate; for loads exceeding 75pF, derating curves in the datasheet show tPLH/tPHL increasing to ~9.0ns. To maintain timing integrity in high-capacitance applications, buffer stages or reduced trace lengths are recommended - the 74ACT10MTC itself is not intended for direct driving of >100pF loads.
Is the 74ACT10MTC RoHS-compliant and lead-free?
Yes, the 74ACT10MTC is lead-free and complies with JEDEC J-STD-020B standard for moisture sensitivity and Pb-free packaging. All packages, including the MTC14 TSSOP variant, were manufactured as lead-free per Fairchild's documentation dated January 2008. No exemptions or alternate material sets apply - the device meets RoHS Directive 2011/65/EU requirements for restricted substances.
Does the 74ACT10MTC include any ESD protection, and what is its HBM rating?
The 74ACT10MTC incorporates built-in ESD protection diodes on all inputs and outputs. Per Fairchild's characterization, it achieves a Human Body Model (HBM) rating of ±2000V - consistent with standard industrial logic ICs of its era. This level of protection supports safe handling during assembly and operation in typical factory environments, though external transient suppressors are still advised in high-noise industrial settings where cable-connected signals may induce surges beyond HBM limits.
