Product details
Overview
DM74ALS1034M from Fairchild Semiconductor is a hex non-inverting driver IC implementing six independent logic identity functions, operating at 4.5–5.5 V supply, with ±15 mA high-level and 24 mA low-level output drive, and guaranteed switching performance over 0°C to +70°C for industrial bus buffering applications.
For engineers reviewing the DM74ALS1034M datasheet, pinout, applications, or equivalent options, key selection considerations include TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), 1–8 ns propagation delay at 50 pF load, SOIC-14 thermal resistance (θJA = 106.5°C/W), and functional compatibility with standard Schottky TTL drivers.
Technical Context
This device belongs to the advanced low-power Schottky (ALS) TTL family, fabricated using oxide-isolated, ion-implanted Schottky process technology. It delivers improved AC performance versus standard Schottky (LS) and low-power Schottky (L) TTL counterparts while maintaining full DC compatibility.
All six drivers operate with identical electrical characteristics: VOH ≥ 2.4 V at IOH = −3 mA, VOL ≤ 0.4 V at IOL = 12 mA, and guaranteed tPLH/tPHL ≤ 8 ns under RL = 500 Ω and CL = 50 pF conditions across the full temperature and voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - supports standard 5 V TTL rail with ±10% tolerance |
| VOH (min) | 2.4 V at IOH = −3 mA - ensures robust HIGH-level interface to downstream TTL/ALS inputs |
| VOL (max) | 0.4 V at IOL = 12 mA - guarantees valid LOW-level recognition under typical bus loading |
| tPLH / tPHL | 1–8 ns - enables reliable operation in 25–100 MHz clock distribution or data strobing |
| IOL / IOH | 24 mA sink / −15 mA source - drives multiple TTL loads (fan-out ≥ 20) without external buffers |
| Operating Temp | 0°C to +70°C - qualified for commercial and industrial ambient environments |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - fully compatible with standard TTL logic families |
Pinout & Package
DM74ALS1034M is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 9, 10, 13 | Input A1–A6 | Independent TTL-compatible digital inputs accepting 0.8 V / 2.0 V thresholds |
| 2, 3, 6, 8, 11, 12 | Output Y1–Y6 | Non-inverting buffered outputs driving up to 24 mA sink / −15 mA source |
| 7 | GND | Ground reference for all logic and power terminals |
| 14 | VCC | +5 V supply terminal; decoupling capacitor required adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Hex non-inverting buffer function | Six independent identity gates enable parallel signal conditioning without inversion |
| ALS TTL process technology | Oxide-isolated, ion-implanted Schottky fabrication ensures lower power and higher speed than LS/L TTL |
| Guaranteed AC specs at 50 pF | Propagation delays validated at realistic capacitive load-no derating needed for board-level design |
| Full temperature/voltage spec coverage | All parameters guaranteed from 0°C to +70°C and 4.5–5.5 V-no corner-case validation required |
| PIN-compatible with legacy TTL | Direct drop-in replacement for 74S1034, 74LS1034, and 74F1034 in SOIC-14 footprint |
Applications
| Industrial Bus Buffering | Legacy System Signal Conditioning |
|---|---|
Use Scenario: Driving multiple TTL loads on a backplane or PCB trace with >30 pF total capacitance. IC Role / Device Role / Timing Role: Non-inverting buffer isolating microcontroller GPIO from high-capacitance bus lines. Use Value: Maintains signal integrity with <8 ns delay and 24 mA drive, eliminating need for discrete transistor arrays. | Use Scenario: Replacing obsolete 74LS1034 in repair or lifecycle-maintenance of 1980s–90s instrumentation. IC Role / Device Role / Timing Role: Pin- and function-identical upgrade preserving original timing margins and layout. Use Value: Same SOIC-14 footprint and electrical behavior, with improved speed/power over LS variant. |

IC Role / Device Role / Timing Role: Current-boosting buffer stage between logic-level outputs and medium-power peripherals. Use Value: Delivers 24 mA sink per channel-sufficient to drive LEDs directly without series resistors in some configurations. | Use Scenario: Expanding limited GPIO count on vintage 8-bit controllers (e.g., Z80, 8085) for peripheral control. IC Role / Device Role / Timing Role: Logic-level translator and fan-out multiplier for address/data/control signals. Use Value: Six independent buffers allow simultaneous expansion of multiple control lines with no added latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALS1034N | Same ALS logic family, identical electrical specs, but in PDIP-14 (N14A) package | Through-hole mounting only; higher θJA (76°C/W) but better mechanical stability | Select when prototyping or repairing legacy through-hole boards where SOIC rework is impractical |
| 74F1034PC | Fast TTL variant: faster tPLH/tPHL (≤4 ns), higher ICC (12–20 mA), wider VCC range (4.5–5.5 V same) | Higher power consumption; less suitable for thermally constrained or battery-backed systems | Choose when propagation delay <4 ns is mandatory and power budget allows ~2× ICC increase |
Compared with SN74ALS1034N and 74F1034PC, the DM74ALS1034M offers optimal balance of speed (≤8 ns), power (ICC ≤14 mA), and surface-mount compatibility in industrial retrofits and space-constrained designs.

FAQ
What is the maximum capacitive load the DM74ALS1034M can drive while maintaining guaranteed timing?
The DM74ALS1034M guarantees switching characteristics-including tPLH and tPHL ≤8 ns-specifically at CL = 50 pF, as defined in the official Fairchild datasheet DS006259. While it may function with higher loads, timing degradation beyond 50 pF is not characterized or warranted. For designs exceeding this, verify timing margins empirically or add series termination.
Is the DM74ALS1034M pin-compatible with the 74LS1034 in the same SOIC-14 package?
Yes-the DM74ALS1034M uses the identical SOIC-14 (M14A) footprint and pinout as the 74LS1034M, with matching input/output assignments and power/ground locations. Its ALS process provides faster switching and lower power, making it a direct drop-in replacement where enhanced performance is acceptable.
Does the DM74ALS1034M support operation at 3.3 V supply?
No-the DM74ALS1034M is specified only for VCC = 4.5 V to 5.5 V per its Recommended Operating Conditions. It lacks 3.3 V logic level compatibility and will not meet VOH/VOL or timing specifications at 3.3 V. For 3.3 V systems, consider modern CMOS buffers such as the 74LVC125.
What is the thermal resistance (θJA) of the DM74ALS1034M package?
The DM74ALS1034M in the M14A SOIC-14 package has a typical junction-to-ambient thermal resistance (θJA) of 106.5°C/W, as measured under standard JEDEC test conditions. This value assumes a two-layer PCB with minimal copper pour; actual thermal performance depends on board layout and airflow.
Can the DM74ALS1034M be used to drive LEDs directly?
Yes-the DM74ALS1034M can sink up to 24 mA per output (IOL = 24 mA), which is sufficient to drive standard indicator LEDs without external transistors. However, ensure VOL remains ≤0.4 V at that current, and confirm LED forward voltage and series resistance (if used) align with the 5 V supply and output capability of the DM74ALS1034M.
