Product details
Overview
74ACT10SC from Fairchild Semiconductor is a triple 3-input NAND gate logic IC operating at 4.5V–5.5V supply, delivering ±24mA output drive, 6.5ns typical propagation delay (tPLH/tPHL), and TTL-compatible input thresholds. It performs combinational logic inversion in digital control, address decoding, and bus interface circuits within industrial PLCs and legacy instrumentation systems.
For engineers reviewing the 74ACT10SC datasheet, pinout, applications, or equivalent options, key selection criteria include its ACT-series 5V-only operation, SOIC-14 package compatibility, guaranteed 24mA sink/source capability, and −40°C to +85°C industrial temperature range.
Technical Context
The 74ACT10SC implements three independent 3-input NAND gates using advanced CMOS technology with TTL-compatible input circuitry. Its input thresholds are fixed at VIH = 2.0V min and VIL = 0.8V max at VCC = 4.5V–5.5V, ensuring robust noise immunity in mixed-signal environments.
Each gate exhibits matched tPLH and tPHL propagation delays under 50pF load, with dynamic output current capability of ±75mA (IOLD/IOHD) for transient pulse handling. Quiescent ICC remains ≤40µA across the full operating temperature range.
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 | 4.5V to 5.5V - restricts use to stable 5V systems; not compatible with 3.3V or wide-range supplies. |
| Output Drive | ±24mA - supports direct driving of multiple TTL inputs or small LEDs without buffer stages. |
| Propagation Delay | 6.5ns typical (tPLH/tPHL, VCC = 5V, CL = 50pF) - ensures timing predictability in synchronous control logic below 100MHz clock domains. |
| Operating Temperature | −40°C to +85°C - qualified for industrial ambient conditions without derating. |
| Input Thresholds | VIH = 2.0V min, VIL = 0.8V max - provides 0.7V noise margin against TTL-level signals at 5V. |
| Quiescent ICC | ≤40µA max - enables low-static-power operation in always-on monitoring subsystems. |
Pinout & Package
74ACT10SC is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body width, with standard gull-wing lead form and 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13 | Inputs A1, B1, C1 | First NAND gate inputs - require clean, slew-rate-compliant signals (≥125mV/ns edge rate). |
| 3 | Output O1 | Inverted AND of pins 1,2,13 - active-low logic output with 0.44V max VOL at 24mA sink. |
| 4, 5, 6 | Inputs A2, B2, C2 | Second NAND gate inputs - electrically isolated from Gate 1; share same VCC/GND reference. |
| 8 | Output O2 | Inverted AND of pins 4,5,6 - drives loads up to 24mA while maintaining VOH ≥3.76V at VCC = 4.5V. |
| 9, 10, 11 | Inputs A3, B3, C3 | Third NAND gate inputs - support identical timing and voltage thresholds as Gates 1 and 2. |
| 12 | Output O3 | Inverted AND of pins 9,10,11 - fully buffered output stage matches performance of O1/O2. |
| 7 | GND | Ground reference for all logic and I/O - must be low-impedance connection to minimize ground bounce. |
| 14 | VCC | +5V supply rail - requires local 0.1µF ceramic decoupling adjacent to pin for AC noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH/VIL thresholds match legacy 74LS devices, enabling drop-in replacement in 5V logic upgrades. |
| High-output drive | ±24mA sourcing/sinking eliminates need for external drivers when interfacing with multiple TTL loads. |
| Low quiescent current | ICC ≤40µA ensures minimal standby power draw in battery-backed or energy-sensitive control modules. |
| Industrial temperature rating | −40°C to +85°C operation supports deployment in uncontrolled enclosures like factory-floor HMIs. |
| JEDEC-standard SOIC package | M14A footprint enables compatibility with legacy PCB layouts and automated assembly processes. |

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 (TI's M14A-equivalent), but manufactured by Texas Instruments. | No functional deviation; validated for same industrial temperature range and 5V supply operation. | Select when TI-sourced supply chain alignment or dual-sourcing strategy is required. |
| 74VHC10M | Higher VCC range (2V–5.5V), lower ICC (≤2µA), but reduced output drive (±8mA) and slower propagation (11ns typ). | Suitable for low-power 3.3V/5V mixed systems but cannot replace 74ACT10SC in high-drive or strict-timing applications. | Choose only if supply voltage flexibility or ultra-low static power outweighs drive strength and speed requirements. |
Compared with SN74ACT10DR and 74VHC10M, the 74ACT10SC offers superior output drive and tighter timing control at 5V, making it optimal for legacy 5V industrial designs requiring robust fanout and deterministic propagation.

FAQ
What is the supply voltage range for the 74ACT10SC?
The 74ACT10SC operates strictly within 4.5V to 5.5V. It is not rated for 3.3V or wider supply ranges. Operation outside this window violates recommended conditions and may cause undefined logic states or accelerated wear. The 74ACT10SC datasheet specifies VIH/VIL thresholds and propagation delays only at 4.5V and 5.5V, confirming its design intent for stable 5V systems.
Can the 74ACT10SC directly drive multiple TTL inputs?
Yes, the 74ACT10SC can directly drive multiple TTL inputs due to its ±24mA output capability and TTL-compatible input thresholds. Each output maintains VOH ≥3.76V and VOL ≤0.44V under 24mA load, satisfying standard TTL VIH (2.0V min) and VIL (0.8V max) requirements. This eliminates the need for additional buffer stages in most 5V logic interconnects.
Is the 74ACT10SC pin-compatible with the 74AC10SC?
No - although both share the same SOIC-14 package and pinout, the 74ACT10SC and 74AC10SC differ in input threshold specifications and recommended supply ranges. The 74AC10SC supports 2.0V–6.0V operation with CMOS thresholds, while the 74ACT10SC requires 4.5V–5.5V and uses TTL-compatible thresholds. Interchangeability requires verification of signal levels and timing margins in the target circuit.
What is the maximum propagation delay of the 74ACT10SC?
The 74ACT10SC has a maximum propagation delay of 10.0ns (tPLH) and 9.5ns (tPHL) at VCC = 5.0V, TA = –40°C to +85°C, and CL = 50pF. These values are guaranteed across the full industrial temperature range and define the worst-case timing budget for synchronous logic design using the 74ACT10SC.
Does the 74ACT10SC support lead-free assembly?
Yes, the 74ACT10SC is lead-free per JEDEC J-STD-020B standard. Its SOIC-14 package (M14A) is qualified for standard reflow profiles used in RoHS-compliant manufacturing. The device's thermal characteristics, including junction-to-ambient resistance and moisture sensitivity level (MSL), align with industry-standard lead-free process requirements.
