Product details
Overview
DM74ALS00ASJ from Fairchild Semiconductor is a quad 2-input NAND gate IC in EIAJ TYPE II SOP-14 package, operating at VCC = 4.5–5.5 V with propagation delays as low as 2 ns (tPHL) and 3 ns (tPLH), rated for 0°C to +70°C industrial temperature range, and delivering 8 mA sink current (IOL) - used in digital logic control, address decoding, and bus interface circuits.
For engineers reviewing the DM74ALS00ASJ datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed AC performance over full VCC/temperature range, Schottky TTL-compatible logic levels, and verified 50 pF load switching behavior per gate.
Technical Context
The DM74ALS00ASJ implements four independent TTL-compatible NAND gates using advanced oxide-isolated, ion-implanted Schottky process technology. Each gate exhibits symmetric input thresholds (VIL = 0.8 V, VIH = 2.0 V) and rail-referenced output drive (VOH ≥ VCC − 2 V, VOL ≤ 0.5 V at IOL = 8 mA).
It operates strictly within 4.5–5.5 V supply range and is specified for 0°C to +70°C free-air temperature. Switching characteristics are guaranteed under RL = 500 Ω and CL = 50 pF conditions, with no internal pull-ups, open-collector, or three-state functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems without regulation margin issues |
| tPHL / tPLH | 2 ns / 3 ns min - enables reliable operation in high-speed digital control loops up to ~200 MHz clock-equivalent edge rates |
| IOL / IOH | 8 mA / −0.4 mA - supports direct driving of multiple standard TTL inputs (fan-out ≥ 20) |
| VIL / VIH | 0.8 V / 2.0 V - provides noise margin >0.4 V against ground bounce and crosstalk in mixed-signal PCBs |
| Operating Temp | 0°C to +70°C - qualified for commercial and industrial ambient environments without derating |
| Input Clamp Voltage | −1.5 V - protects inputs during transient overvoltage or hot-insertion events |
Pinout & Package
DM74ALS00ASJ is housed in a 14-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3 mm wide (Package Number M14D), with gull-wing leads and standard 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Input (A/B per gate) | Two dedicated inputs per NAND gate; all inputs electrically identical with VIH/VIL thresholds |
| 3, 6, 10, 13 | Output (Y per gate) | Active-pull active-push totem-pole outputs - no open-drain or three-state capability |
| 7 | GND | Ground reference for all logic and power domains; requires low-impedance PCB connection |
| 14 | VCC | Positive supply terminal; decoupling capacitor (0.1 µF) required within 10 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed AC specs at 50 pF | Enables predictable timing in real-world PCB traces with typical capacitive loading |
| Oxide-isolated Schottky TTL process | Delivers faster switching than standard LS-TTL while maintaining backward compatibility |
| Full temp/VCC range validation | Eliminates need for design margining in uncontrolled thermal environments |
| Pin-for-pin compatible with 74S00/74LS00 | Allows drop-in replacement in legacy designs without layout changes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALS00AN | Same ALS logic family, identical electrical specs, but in PDIP-14 (N14A) package | Preferred for through-hole prototyping and legacy board repair where SOP footprint is unavailable | Select when manual soldering, socketing, or thermal mass requirements favor DIP over SOP |
| DM74ALS00AM | Identical function and specs, but in JEDEC SOIC-14 (M14A) package with 0.150" body width | Suitable for automated SMT assembly on boards designed for narrow-body SOIC footprints | Choose when board layout uses MS-012 compliant land patterns instead of EIAJ TYPE II |
Compared with SN74ALS00AN and DM74ALS00AM, the DM74ALS00ASJ offers identical logic behavior and timing but differs in mechanical form factor - its EIAJ TYPE II SOP-14 body width (5.3 mm) enables higher density routing than PDIP and fits distinct land patterns versus JEDEC SOIC, requiring footprint verification before substitution.

Manufacturer
Fairchild Semiconductor was a U.S.-based semiconductor company specializing in analog and mixed-signal ICs, power management, and logic families before its acquisition by ON Semiconductor in 2016.
The DM74ALS00ASJ belongs to the 74ALS (Advanced Low-Power Schottky) logic series, engineered for improved speed-power trade-offs in mid-1980s digital systems where TTL compatibility and reliability were critical.
FAQ
What logic family does the DM74ALS00ASJ belong to, and how does it differ from standard 74LS?
The DM74ALS00ASJ belongs to the 74ALS (Advanced Low-Power Schottky) family. It improves upon 74LS with faster propagation delays (2–11 ns vs. 15–40 ns), lower power consumption (ICC ≈ 0.85 mA vs. ~2 mA), and tighter voltage thresholds. The DM74ALS00ASJ retains full pin and functional compatibility with 74LS00, enabling direct upgrades in existing designs without logic or layout changes.
Is the DM74ALS00ASJ pin-compatible with the SN74ALS00AN?
Yes - the DM74ALS00ASJ and SN74ALS00AN share identical pinout, logic function, and electrical specifications. The only difference is package type: DM74ALS00ASJ uses EIAJ TYPE II SOP-14, while SN74ALS00AN uses PDIP-14. Both are fully interchangeable at the schematic level, though PCB footprint and thermal management must be adapted accordingly for the DM74ALS00ASJ.
What is the maximum capacitive load the DM74ALS00ASJ can drive while maintaining guaranteed timing?
The DM74ALS00ASJ's switching characteristics are guaranteed at CL = 50 pF, as specified in the datasheet's "Switching Characteristics" table. Driving loads beyond 50 pF may increase propagation delay unpredictably and is not characterized. For reliable timing in DM74ALS00ASJ-based designs, keep total net capacitance (trace + input + probe) ≤50 pF or add appropriate buffering.
Does the DM74ALS00ASJ support three-state or open-collector outputs?
No - the DM74ALS00ASJ features standard totem-pole (push-pull) outputs only, with no three-state, open-collector, or open-drain capability. All four gates provide active HIGH and LOW drive (IOH = −0.4 mA, IOL = 8 mA). If bus-sharing or wired-AND functionality is needed, external pull-up resistors or additional logic must be used with the DM74ALS00ASJ.
What is the recommended decoupling strategy for the DM74ALS00ASJ in high-speed layouts?
A 0.1 µF ceramic capacitor should be placed as close as possible (≤10 mm) between VCC (pin 14) and GND (pin 7) of each DM74ALS00ASJ device. For boards with multiple units, add a bulk 4.7–10 µF tantalum or aluminum electrolytic capacitor per power rail segment. This minimizes VCC sag and ground bounce during simultaneous output transitions in the DM74ALS00ASJ.
