Product details
Overview
DM74ALS11AN from Fairchild Semiconductor is a triple 3-input AND gate IC in a 14-lead PDIP package, operating at 4.5–5.5 V supply, with propagation delays as low as 2 ns (tPLH/tPHL), output drive capability of ±30 mA, and guaranteed performance across 0°C to +70°C for digital logic control in industrial timing and signal routing applications.
For engineers reviewing the DM74ALS11AN datasheet, pinout, applications, or equivalent options, key selection considerations include its TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V), 50 pF load switching specs, SOIC/PDIP dual-package availability, and functional compatibility with 74LS11 and 74S11 families.
Technical Context
The DM74ALS11AN implements three independent AND gates using advanced oxide-isolated, ion-implanted Schottky TTL technology, enabling improved AC performance over standard Schottky and low-power Schottky TTL counterparts. Each gate accepts three inputs (A, B, C) and produces Y = A·B·C with rail-to-rail compatible logic levels.
It operates within a recommended VCC range of 4.5–5.5 V and supports full-temperature-range guaranteed switching characteristics (tPLH ≤ 13 ns, tPHL ≤ 10 ns at CL = 50 pF, RL = 500 Ω), with input clamp voltage (VIK = −1.5 V) and output drive current (IOL = 8 mA, IOH = −0.4 mA) specified per gate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures stable operation with standard 5 V TTL power rails |
| Propagation Delay | tPLH/tPHL ≤ 13/10 ns - enables high-speed combinational logic in clocked systems |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V - guarantees interoperability with 74LS, 74S, and other TTL families |
| Output Drive | IOL = 8 mA, IOH = −0.4 mA - sufficient fan-out for driving multiple TTL inputs without buffering |
| Operating Temp | 0°C to +70°C - rated for commercial-grade embedded and industrial control environments |
| Input Clamp Voltage | VIK = −1.5 V - protects against negative transient spikes on input lines |
Pinout & Package
DM74ALS11AN is housed in a 14-lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" wide, with 0.100" lead pitch and through-hole mounting compatibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LS11N | Higher propagation delay (15–22 ns), lower IOL (8 mA same), identical pinout and VCC range | Marginally slower but widely available; suitable where <20 ns delay is acceptable | Select when cost sensitivity outweighs speed requirement and LS-family stock is preferred |
| SN74F11N | Faster tPLH/tPHL (≤ 5.5 ns), higher ICC (12 mA), same 14-pin PDIP package and logic function | Better suited for high-frequency clocked systems but draws more supply current | Choose for timing-critical paths where speed >5 ns improvement justifies increased power |
Compared with SN74LS11N and SN74F11N, the DM74ALS11AN delivers superior speed-to-power ratio: faster than LS by up to 50% while consuming less than half the supply current of F-series, making it optimal for balanced-performance commercial logic designs.

FAQ
What logic family does the DM74ALS11AN belong to?
The DM74ALS11AN belongs to Fairchild's Advanced Low-Power Schottky (ALS) TTL logic family. It combines Schottky clamping for speed with optimized transistor sizing for reduced power, distinguishing it from standard LS and faster F-series families. The DM74ALS11AN maintains full compatibility with TTL voltage thresholds and drive capabilities while improving propagation delay and supply current efficiency.
Is the DM74ALS11AN pin-compatible with the 74LS11?
Yes, the DM74ALS11AN is pin-for-pin compatible with the SN74LS11N and other 74LS11 variants. Its 14-pin PDIP footprint, input/output assignments, and power pin locations (VCC = Pin 14, GND = Pin 7) match exactly. This allows direct replacement in existing designs without PCB modification, provided timing margins accommodate the improved speed of the ALS version.
What is the maximum operating temperature range for the DM74ALS11AN?
The DM74ALS11AN is rated for operation from 0°C to +70°C, consistent with commercial-grade TTL specifications. Its electrical characteristics-including propagation delay, output voltage levels, and input thresholds-are guaranteed across this full range. The device also supports storage from −65°C to +150°C, making it suitable for non-operational environmental exposure in industrial enclosures.
Can the DM74ALS11AN drive LED indicators directly?
The DM74ALS11AN can sink up to 8 mA per output (IOL = 8 mA) but sources only −0.4 mA (IOH). Therefore, it can directly drive LEDs in active-low configuration (anode to VCC, cathode to output), assuming a series resistor limits current to ≤8 mA. For active-high LED drive, an external pull-up or buffer is required due to its weak sourcing capability. Always verify voltage drop and brightness requirements using the DM74ALS11AN's VOL = 0.35–0.5 V at 8 mA.
Does the DM74ALS11AN require decoupling capacitors in typical applications?
Yes, the DM74ALS11AN requires local 0.1 µF ceramic decoupling capacitors placed between VCC (Pin 14) and GND (Pin 7), as close as possible to the package. This mitigates switching noise and prevents supply rail droop during simultaneous output transitions-especially critical given its sub-15 ns propagation delays and shared VCC/GND among three gates. Omission may cause erratic logic behavior or increased EMI in dense layouts.
