Product details
Overview
DM74ALS1034MX from Fairchild Semiconductor is a hex non-inverting driver IC implementing six independent logic identity functions, with 5.5 V max supply voltage, 24 mA low-level output drive, and guaranteed switching performance at 50 pF load across 0°C to +70°C. It serves as a buffered signal repeater in TTL-based bus interface and level-shifting circuits.
For engineers reviewing the DM74ALS1034MX datasheet, pinout, applications, or equivalent options, key selection factors include its SOIC-14 package, −15 mA high-level output current, input clamp voltage of −1.2 V, and compatibility with standard ALS TTL logic families.
Technical Context
This device belongs to the Advanced Low-Power Schottky (ALS) TTL family and uses oxide-isolated, ion-implanted Schottky process technology. It delivers improved AC performance over standard Schottky and Low-Power Schottky TTL counterparts while maintaining functional and pin-for-pin compatibility.
The DM74ALS1034MX operates within a 4.5 V to 5.5 V supply range and guarantees propagation delays of 1–8 ns (tPLH/tPHL) under 50 pF capacitive loading and 500 Ω resistive load conditions. Its input thresholds are VIH ≥ 2.0 V and VIL ≤ 0.8 V, ensuring robust noise margin in mixed-logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - supports stable operation across standard TTL supply tolerance |
| IOL / IOH | 24 mA / −15 mA - drives standard TTL loads without external buffering |
| tPLH / tPHL | 1–8 ns - enables high-speed bus driving up to ~125 MHz effective toggle rate |
| VIH / VIL | ≥2.0 V / ≤0.8 V - provides 0.4 V noise margin for reliable logic discrimination |
| VIK | −1.2 V - protects inputs against negative transients during hot insertion or ESD events |
| ICC (Outputs HIGH) | 3–6 mA - low quiescent power vs. standard LS-TTL, reducing system heat load |
Pinout & Package
DM74ALS1034MX is supplied in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with thermal resistance θJA = 106.5°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Input A1–A4 | Non-inverting logic inputs accepting standard TTL voltage levels |
| 2, 5, 11, 14 | Output Y1–Y4 | Active-pull output drivers capable of sourcing −15 mA or sinking 24 mA |
| 3, 6, 12 | GND | Common ground reference for all six channels and internal circuitry |
| 7 | VCC | Positive supply terminal; must be decoupled locally to suppress switching noise |
| 8, 9 | A5, A6 | Additional inputs for fifth and sixth driver channels |
| 10, 11 | Y5, Y6 | Corresponding outputs for fifth and sixth driver channels |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALS1034N | Same ALS TTL logic family, identical DC/AC specs, but in PDIP-14 package (θJA = 76.0°C/W) | Better thermal performance in through-hole prototyping or low-volume industrial assemblies | Select when board space allows DIP footprint and manual soldering is preferred |
| 74F1034PC | Fast TTL variant: faster tPLH/tPHL (3.5 ns typ), higher ICC (12 mA), lower noise immunity (VIH = 2.0 V same, but lower VIL margin) | Suitable for higher-speed designs where propagation delay dominates over power or noise margin | Choose only if timing budget requires <4 ns delay and system noise environment is controlled |
Compared with SN74ALS1034N and 74F1034PC, the DM74ALS1034MX offers optimal balance of speed, power, and thermal profile in surface-mount production-its SOIC-14 footprint supports automated assembly while maintaining full ALS TTL compatibility and proven reliability in long-lifecycle industrial deployments.

FAQ
What is the maximum operating temperature for the DM74ALS1034MX?
The DM74ALS1034MX is rated for operation from 0°C to +70°C ambient temperature. All electrical characteristics-including propagation delay, output drive, and input thresholds-are guaranteed across this full range. Thermal design must account for its SOIC-14 θJA of 106.5°C/W; derating is not required within the specified ambient window.
Is the DM74ALS1034MX pin-compatible with older 74LS1034 devices?
Yes, the DM74ALS1034MX is functionally and pin-for-pin compatible with both 74LS1034 and 74S1034 devices in the same SOIC-14 package. Its input/output thresholds, drive strength, and timing behavior align with industry-standard ALS TTL specifications, allowing direct substitution without layout changes.
What is the input clamp voltage specification for DM74ALS1034MX?
The DM74ALS1034MX specifies an input clamp voltage (VIK) of −1.2 V when VCC = 4.5 V and II = −18 mA. This clamping action protects inputs from negative transients during hot-swap events or ESD discharge, a critical feature in industrial backplane and modular system applications.
Can DM74ALS1034MX drive standard TTL loads directly?
Yes, the DM74ALS1034MX can directly drive standard TTL loads: its IOL = 24 mA and IOH = −15 mA meet or exceed the input current requirements of one standard TTL unit load (IIL = −1.6 mA, IIH = 40 µA). It supports up to 6 standard TTL inputs per output without external buffering.
Does DM74ALS1034MX require external pull-up resistors on its outputs?
No, the DM74ALS1034MX features active pull-up circuitry and does not require external pull-up resistors. Its outputs are fully buffered CMOS-compatible TTL drivers capable of sourcing −15 mA and sinking 24 mA, delivering rail-to-rail logic swings under defined load conditions.
