Product details
Overview
DM74ALS10AM from Fairchild Semiconductor is a triple 3-input NAND gate IC in 14-lead SOIC (M14A) package, operating at 4.5–5.5 V supply, with propagation delays as low as 2 ns (tPLH/tPHL), ±0.4 mA high-level and 8 mA low-level output drive, and guaranteed performance across 0°C to +70°C. It serves as a core combinational logic element in TTL-based digital control and address decoding circuits.
For engineers reviewing the DM74ALS10AM datasheet, pinout, applications, or equivalent options, key selection considerations include its ALS-family speed-power trade-off, SOIC thermal resistance (θJA = 116.0°C/W), input voltage thresholds (VIL = 0.8 V, VIH = 2.0 V), and compatibility with legacy 74-series TTL board designs.
Technical Context
The DM74ALS10AM implements three independent 3-input NAND gates using advanced oxide-isolated, ion-implanted Schottky TTL technology. Each gate accepts standard TTL-level inputs and delivers rail-referenced CMOS-compatible outputs under load conditions up to 8 mA sink current.
It operates within a recommended VCC range of 4.5–5.5 V and supports full industrial temperature range (0°C to +70°C) with guaranteed switching characteristics at 50 pF capacitive load. Its logic function Y = A·B·C is strictly defined per gate, with no internal feedback or enable controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures interoperability with standard 5 V TTL power rails and tolerance against supply ripple. |
| tPLH / tPHL | 2 ns (min) to 11 ns (max) - Enables use in sub-20 ns clock domains and fast address strobe generation. |
| IOL / IOH | 8 mA sink / −0.4 mA source - Supports direct driving of multiple standard TTL inputs (fan-out ≥ 20). |
| VIL / VIH | 0.8 V / 2.0 V - Matches legacy TTL input thresholds for seamless integration into existing 74-series systems. |
| Operating Temp | 0°C to +70°C - Qualified for commercial-grade embedded control and instrumentation applications. |
| θJA | 116.0°C/W - Defines thermal derating limit in SOIC-14; requires PCB copper area for sustained 2.4 mA ICC operation. |
Pinout & Package
DM74ALS10AM is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150″ narrow body (Package Number M14A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Input A/B/C of Gate 1 | Three independent logic inputs for first NAND gate; all referenced to GND, compatible with TTL voltage levels. |
| 4 | Output Y1 | Active-low NAND output of Gate 1; sinks up to 8 mA, sources −0.4 mA. |
| 5, 6, 13 | Input A/B/C of Gate 2 | Inputs for second NAND gate; pin 13 is shared layout position but electrically isolated from other gates. |
| 12 | Output Y2 | Output of Gate 2; identical electrical specs to Pin 4. |
| 10, 9, 8 | Input A/B/C of Gate 3 | Inputs for third NAND gate; arranged in reverse order to match JEDEC SOIC pinout convention. |
| 11 | Output Y3 | Output of Gate 3; fully independent, same drive capability as Pins 4 and 12. |
| 7 | GND | Ground reference for all logic and power terminals; must be low-impedance connection. |
| 14 | VCC | +5 V supply input; bypass capacitor (0.1 µF) required adjacent to this pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| ALS process technology | Oxide-isolated, ion-implanted Schottky TTL - Delivers faster switching than LS while maintaining lower power than standard Schottky. |

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 |
|---|---|---|---|
| SN74ALS10N | Same ALS logic family, but in 14-lead PDIP (N14A); θJA = 86.5°C/W; slightly higher ICC (0.65 mA typ. outputs HIGH). | Preferred for through-hole prototyping or legacy repair where SOIC reflow is unavailable. | Select when manual soldering or socket-based testing is required; not suitable for high-density SMT production. |
| 74HC10PW | CMOS-based (74HC), 3–6 V VCC range, 100 µA ICC, but VIH = 3.5 V min - incompatible with 5 V TTL input levels without level shifting. | Used in mixed-voltage systems where ultra-low static power is critical and input signal conditioning is acceptable. | Choose only if redesigning for 3.3 V logic or adding discrete level shifters; not a direct interface replacement for DM74ALS10AM. |
Compared with SN74ALS10N and 74HC10PW, the DM74ALS10AM uniquely balances TTL-compatible signaling, SOIC manufacturability, and sub-10 ns speed in commercial-temperature applications - making it optimal for cost-sensitive, volume-produced 5 V digital control boards where pin compatibility and thermal behavior are design-critical.

Manufacturer
Fairchild Semiconductor was a U.S.-based semiconductor manufacturer specializing in analog and logic ICs, later acquired by ON Semiconductor in 2016. Its legacy logic families remain widely deployed in industrial and instrumentation systems.
The DM74ALS10AM belongs to the Advanced Low-Power Schottky (ALS) TTL logic family, designed specifically to improve speed-power efficiency over earlier LS and S series while maintaining full pin and functional compatibility with 74-series board layouts.
FAQ
What logic family does the DM74ALS10AM belong to, and how does it differ from standard 74LS10?
The DM74ALS10AM belongs to the Advanced Low-Power Schottky (ALS) TTL family. Compared to 74LS10, it offers faster propagation delays (2–11 ns vs. 3–15 ns), lower ICC (0.6 mA vs. 1.6 mA typ. with outputs HIGH), and improved noise immunity due to tighter VIH/VIL specifications. The DM74ALS10AM maintains identical pinout and logic function, enabling direct replacement in most 74LS10 designs without circuit modification.
Is the DM74ALS10AM RoHS compliant?
The DM74ALS10AM was manufactured prior to RoHS enforcement and is not RoHS compliant. It contains lead in the die attach and solder finish per JEDEC MS-012 SOIC construction standards of the 1990s. For RoHS-compliant alternatives, consult Aetrix's qualified replacements list - the DM74ALS10AM remains available for legacy repair and industrial maintenance where exemptions apply.
What is the maximum capacitive load the DM74ALS10AM can drive while maintaining specified tPLH/tPHL?
The DM74ALS10AM's switching characteristics - including tPLH and tPHL - are guaranteed only at CL = 50 pF, as specified in the datasheet. Driving loads exceeding 50 pF will increase propagation delay nonlinearly and may cause marginal timing in high-speed designs. For >50 pF loads, buffer staging or layout optimization (shorter traces, reduced parallel net count) is required to maintain timing integrity for the DM74ALS10AM.
Can the DM74ALS10AM operate reliably at VCC = 4.2 V?
No. The DM74ALS10AM's recommended minimum VCC is 4.5 V, and its electrical characteristics - including VOH, VOL, and propagation delay - are not guaranteed below that threshold. At 4.2 V, output high voltage may fall below 2.4 V, increasing risk of logic misinterpretation downstream. System designs must regulate VCC to ≥4.5 V to ensure correct operation of the DM74ALS10AM.
Does the DM74ALS10AM support mixed-voltage interfacing, such as connecting to 3.3 V microcontrollers?
The DM74ALS10AM is a 5 V-only TTL device with VIH = 2.0 V min and VIL = 0.8 V max, so it can accept 3.3 V logic HIGH signals safely. However, its VOH ≈ VCC − 2 V (≈3.0 V at VCC = 5.0 V) falls below typical 3.3 V input HIGH thresholds (≥2.6 V for most), risking marginal recognition. Direct interfacing requires verification of receiver VIH spec; level-shifting is recommended for robust 3.3 V system integration with the DM74ALS10AM.
