Product details
Overview
DM74ALS11AMX from Fairchild Semiconductor is a triple 3-input AND gate IC in 14-lead SOIC package, operating at 4.5–5.5 V supply, with propagation delays as low as 2 ns (tPLH/tPHL), ±0.4 mA high-level output drive, and 8 mA low-level sink capability - used for combinational logic in industrial control panels and digital instrumentation signal routing.
For engineers reviewing the DM74ALS11AMX datasheet, pinout, applications, or equivalent options, key selection considerations include guaranteed AC performance over full temperature range (0°C to +70°C), compatibility with legacy TTL systems, and SOIC packaging for surface-mount reliability in space-constrained PCBs.
Technical Context
The DM74ALS11AMX implements three independent AND gates using advanced oxide-isolated, ion-implanted Schottky TTL process, ensuring stable logic behavior across VCC = 4.5–5.5 V and TA = 0°C to +70°C. Each gate accepts three inputs (A, B, C) and produces Y = A·B·C with defined VIH ≥ 2.0 V and VIL ≤ 0.8 V.
It delivers guaranteed switching characteristics at CL = 50 pF, with tPLH/tPHL specified from 2 ns (typical) to 13 ns (max), and supports fan-out of 20 LS-TTL loads. Output drive meets IOH = −0.4 mA and IOL = 8 mA under recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures interoperability with standard 5 V TTL logic rails without level-shifting. |
| Propagation Delay | 2 ns (min) to 13 ns (max) - enables reliable timing in sub-20 ns synchronous logic paths. |
| Output Drive | IOL = 8 mA / IOH = −0.4 mA - sufficient to drive 20 LS-TTL inputs directly. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - provides noise margin >0.4 V under worst-case VCC and temperature. |
| Operating Temp | 0°C to +70°C - qualified for commercial-grade industrial control and test equipment environments. |
| Package | SOIC-14 (JEDEC MS-012, 0.150" narrow) - surface-mount compatible with automated assembly and thermal resistance θJA = 116.0°C/W. |
Pinout & Package
DM74ALS11AMX is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body width, with gull-wing leads and standard pin spacing of 0.050".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Gate 1 Inputs (A1, B1, C1) | Three independent logic inputs for first AND gate; all must be HIGH to assert output. |
| 4 | Gate 1 Output (Y1) | Active-HIGH open-collector-compatible output; sinks up to 8 mA. |
| 5, 6, 7 | Gate 2 Inputs (A2, B2, C2) | Inputs for second independent AND function; electrically isolated from Gate 1. |
| 8 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance connection. |
| 9, 10, 11 | Gate 3 Inputs (A3, B3, C3) | Inputs for third AND gate; identical electrical specs and timing to Gates 1 and 2. |
| 12 | Gate 3 Output (Y3) | Third independent AND output; shares same VOH/VOL specs and drive strength. |
| 13 | VCC | Positive supply rail (4.5–5.5 V); decoupling capacitor required near pin for noise immunity. |
| 14 | Gate 2 Output (Y2) | Second AND output; fully buffered, not open-drain - drives HIGH actively. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent AND gates | Three fully isolated 3-input logic functions in one SOIC-14 package - reduces board area vs. discrete gate arrays. |
| Guaranteed AC specs at 50 pF | Propagation delay validated at realistic load capacitance - eliminates guesswork in timing-critical designs. |
| Full temperature & voltage coverage | All switching and DC parameters guaranteed from 0°C to +70°C and VCC = 4.5–5.5 V - no derating needed for industrial ambient. |
| Schottky TTL process | Oxide-isolated, ion-implanted construction - improves speed-power trade-off vs. standard TTL and LSTTL. |
| Pin-for-pin compatibility | Direct replacement for 74S11 and 74LS11 in SOIC footprint - enables drop-in upgrade without layout change. |

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 |
|---|---|---|---|
| SN74ALS11DR | Same ALS family, SOIC-14, identical DC/AC specs; TI-manufactured with different lot traceability and minor packaging marking variance. | No functional difference; qualified for same commercial temp range and 5 V operation. | Select when sourcing from TI-authorized channels or requiring TI-specific compliance documentation. |
| 74VHC11M | CMOS-based, wider VCC range (2–5.5 V), lower ICC (<1 µA), but slower tPD (max 7.5 ns at 5 V, 50 pF) and reduced noise immunity (VIH = 3.5 V min). | Better for battery-powered or mixed-voltage systems; unsuitable where TTL-level input compatibility is mandatory. | Choose only if migrating from TTL to CMOS logic families and redesigning input drive sources. |
Compared with SN74ALS11DR, DM74ALS11AMX offers identical functionality and timing but differs in manufacturer qualification and RoHS status history; versus 74VHC11M, DM74ALS11AMX maintains strict TTL input compatibility and faster worst-case propagation, essential for legacy system upgrades.

FAQ
What is the maximum operating temperature for DM74ALS11AMX?
The DM74ALS11AMX is rated for free-air operating temperatures from 0°C to +70°C, with all electrical and switching specifications guaranteed across this full range. It is not qualified for extended or industrial temperature grades (−40°C to +85°C). Thermal derating is not required within the specified range, and θJA = 116.0°C/W applies to the SOIC package under standard JEDEC test conditions.
Is DM74ALS11AMX pin-compatible with 74LS11 in SOIC package?
Yes, DM74ALS11AMX is pin-for-pin compatible with the 74LS11 in SOIC-14 (M14A) package, sharing identical pin assignments, logic function, and DC interface levels. This allows direct substitution in existing 74LS11-based designs without PCB modification, though users should verify timing margins due to faster propagation delays in the ALS variant.
Does DM74ALS11AMX support mixed-voltage operation (e.g., 3.3 V inputs)?
No, DM74ALS11AMX is a 5 V-only TTL-family device. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive are specified only for VCC = 4.5–5.5 V. Applying 3.3 V logic signals risks unreliable HIGH recognition and violates recommended operating conditions; level translation is required for interfacing with 3.3 V systems.
What is the output structure of DM74ALS11AMX - open-collector or push-pull?
DM74ALS11AMX features standard TTL totem-pole (push-pull) outputs - not open-collector. Each output actively drives both HIGH and LOW states, with VOH ≥ VCC − 2 V (at IOH = −0.4 mA) and VOL ≤ 0.5 V (at IOL = 8 mA). This enables direct interfacing with other TTL and LS-TTL inputs without pull-up resistors.
Can DM74ALS11AMX replace DM74ALS11AN on the same PCB?
Yes, DM74ALS11AMX and DM74ALS11AN share identical logic function, pinout, and electrical specifications - differing only in package (SOIC vs. PDIP). A PCB designed for the PDIP version cannot physically accept the SOIC part without footprint revision, but schematic-level replacement is fully valid; the "X" suffix denotes tape-and-reel packaging, not functional variation.
