Product details
Overview
DM74ALS10AN from Fairchild Semiconductor is a triple 3-input NAND gate in a 14-lead PDIP package, operating at 4.5–5.5 V supply, with propagation delays as low as 2 ns (tPLH/tPHL), 8 mA sink current (IOL), and guaranteed performance across 0°C to +70°C for industrial logic control systems.
For engineers reviewing the DM74ALS10AN datasheet, pinout, applications, or equivalent options, key selection criteria include TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), output drive capability under 50 pF load, AC performance validation over full temperature and voltage range, and PDIP package suitability for through-hole prototyping and legacy board replacement.
Technical Context
This device implements three independent NAND logic functions (Y = A·B·C) using advanced oxide-isolated, ion-implanted Schottky TTL technology. It delivers improved AC performance versus standard Schottky and low-power Schottky TTL counterparts while maintaining functional and pin-for-pin compatibility.
Each gate features TTL-compatible input voltage thresholds, rail-to-rail output swing under specified loads, and guaranteed switching characteristics at 50 pF capacitive load. The design supports direct interface with other 74ALS, 74LS, and 74S family devices without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures stable operation with standard +5 V supply rails and tolerance for ripple or aging. |
| tPLH / tPHL | 2 ns (min) to 11 ns (max) - Enables high-speed combinational logic in clocked state machines and address decoding. |
| IOL / IOH | 8 mA sink / −0.4 mA source - Drives multiple TTL inputs or small LEDs directly without external buffers. |
| VIL / VIH | 0.8 V / 2.0 V - Guarantees noise-immune recognition of LOW/HIGH logic levels across temperature and voltage extremes. |
| Operating Temp | 0°C to +70°C - Qualified for commercial and industrial ambient environments without derating. |
| ICC (Outputs HIGH) | 0.32–0.6 mA - Low quiescent power per gate, supporting dense logic arrays with minimal thermal impact. |
Pinout & Package
DM74ALS10AN is housed in a 14-lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" wide, with through-hole mounting and standard 0.1" pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Input A, B, C of Gate 1 | Three independent logic inputs for first NAND gate; compatible with standard TTL voltage levels. |
| 4 | Output Y1 | Active-low NAND output of Gate 1; sinks up to 8 mA at VOL ≤ 0.5 V. |
| 5, 6, 13 | Input A, B, C of Gate 2 | Inputs for second NAND gate; electrically isolated and identical in timing/specs to Gate 1. |
| 12 | Output Y2 | Output of Gate 2; shares same DC/AC specs and loading behavior as Y1. |
| 8, 9, 10 | Input A, B, C of Gate 3 | Inputs for third NAND gate; fully independent with no internal coupling or crosstalk. |
| 11 | Output Y3 | Output of Gate 3; enables triple parallel logic evaluation in single-package footprint. |
| 7 | GND | Power return reference for all gates; must be low-impedance connection to minimize ground bounce. |
| 14 | VCC | +5 V supply input; requires local 0.1 µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Triple 3-input NAND function | Three independent logic gates in one PDIP-14 package reduce board space and interconnect count vs discrete solutions. |
| Guaranteed AC specs at 50 pF | Propagation delay validated with realistic capacitive loading-no derating needed for typical PCB trace + input capacitance. |
| TTL-compatible input thresholds | VIL ≤ 0.8 V and VIH ≥ 2.0 V ensure interoperability with 74LS, 74S, and other ALS-family devices without level shifters. |
| Oxide-isolated Schottky process | Enables faster switching and lower power than standard bipolar TTL while retaining ruggedness and ESD tolerance. |
| Full temperature/voltage rating | All parameters specified from 0°C to +70°C and VCC = 4.5–5.5 V-no hidden corners requiring design margining. |
Applications
| Industrial Control Logic | Legacy System Repair |
|---|---|
Use Scenario: Decoding PLC I/O address lines where three enable signals must be AND-NOT gated before enabling a peripheral latch. IC Role / Device Role / Timing Role: Performs synchronous 3-input NAND logic with sub-10 ns delay to meet tight setup/hold windows in 8-bit microcontroller bus cycles. Use Value: Eliminates need for multiple 2-input NANDs and inverters, reducing component count and propagation skew across control paths. | Use Scenario: Replacing obsolete 74S10 or 74LS10 in vintage test equipment where board layout prohibits SMT rework. IC Role / Device Role / Timing Role: Drop-in PDIP replacement preserving original footprint, pinout, and logic function without modifying PCB traces or firmware. Use Value: Maintains system timing integrity while restoring reliability-no redesign or requalification required. |
| Power-On Reset Sequencing | LED Driver Enable Logic |
Use Scenario: Generating a delayed system reset signal only after VCC, clock, and watchdog signals are all valid. IC Role / Device Role / Timing Role: Acts as a 3-input voter gate whose output goes LOW only when all three upstream status signals are HIGH. Use Value: Provides deterministic, glitch-free reset assertion with predictable delay (<11 ns max), avoiding race conditions during boot. | Use Scenario: Enabling multiplexed LED displays where column drivers require active-LOW enable synchronized with row scan timing. IC Role / Device Role / Timing Role: Combines three timing/control signals (scan phase, brightness select, blanking) into a single NAND-enable output. Use Value: Delivers 8 mA sink current sufficient to drive LED driver IC inputs directly-no additional buffer stage needed. |
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 | Identical logic function, pinout, and DC specs; TI-manufactured version with same ALS process and 0°C to +70°C rating. | No functional or timing difference; qualified for same industrial control and repair use cases. | Select when sourcing from TI-distributed channels or requiring TI-specific documentation and support. |
| DM74LS10N | Lower speed (15 ns max tPD), higher ICC (2.5 mA per gate), but identical PDIP-14 pinout and VIL/VIH thresholds. | Suitable for cost-sensitive or lower-frequency designs where 2–3 ns extra delay is acceptable. | Choose for legacy LS-TTL system compatibility or where power efficiency is secondary to procurement availability. |
Compared with SN74ALS10N, DM74ALS10AN offers identical performance and form factor but different manufacturer traceability; versus DM74LS10N, it delivers 30% faster propagation and 25% lower quiescent current-critical for timing-critical or thermally constrained layouts.

FAQ
What logic function does the DM74ALS10AN implement?
The DM74ALS10AN implements three independent 3-input NAND gates (Y = A·B·C). Each gate operates with TTL-compatible input thresholds and delivers rail-referenced outputs capable of sinking 8 mA. Its truth table confirms LOW output only when all three inputs are HIGH-enabling universal logic synthesis in combinational circuits.
Is the DM74ALS10AN pin-compatible with older 74-series NAND gates?
Yes, the DM74ALS10AN is functionally and pin-for-pin compatible with 74S10 and 74LS10 devices. Its PDIP-14 pinout matches industry-standard assignments for triple 3-input NANDs-including shared VCC (pin 14), GND (pin 7), and identical input/output terminal mapping-allowing direct replacement without PCB modification.
What is the maximum operating temperature range for the DM74ALS10AN?
The DM74ALS10AN is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade specification is explicitly guaranteed across the full VCC range (4.5–5.5 V), with all electrical parameters-including propagation delay, VOL, and IOL-validated within this interval per the Fairchild DS006180 datasheet.
Can the DM74ALS10AN drive standard TTL inputs directly?
Yes, the DM74ALS10AN can drive standard TTL inputs directly. With an output sink current capability of 8 mA and VOL ≤ 0.5 V at IOL = 8 mA, it meets the fan-out requirement for driving up to 20 standard TTL loads (each drawing ~0.4 mA), satisfying the classic TTL fan-out specification without external buffering.
Does the DM74ALS10AN require external decoupling capacitors?
Yes, the DM74ALS10AN requires a 0.1 µF ceramic decoupling capacitor placed as close as possible to pins 14 (VCC) and 7 (GND). This mitigates high-frequency supply noise generated during fast output transitions, ensuring stable logic levels and preventing false triggering in adjacent gates or downstream circuitry.
