onsemi DM74ALS133MX

Overview

DM74ALS133MX from Fairchild Semiconductor is a 13-input NAND gate IC in 16-lead SOIC (M16A) package, operating at VCC = 4.5–5.5 V, with propagation delays as low as 3 ns (tPLH) and 5 ns (tPHL), rated for 0°C to +70°C industrial temperature range, and delivering 8 mA sink current (IOL) - used in high-density combinational logic control circuits.

For engineers reviewing the DM74ALS133MX datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed AC performance over full VCC/temperature range, Schottky TTL compatibility, and verified 13-input single-gate NAND functionality per JEDEC MS-012 footprint.

Technical Context

The DM74ALS133MX implements a single 13-input NAND function with active-low output logic: output Y is LOW only when all 13 inputs (A–M) are HIGH; otherwise, Y is HIGH. It uses oxide-isolated, ion-implanted Schottky TTL process for improved speed and noise immunity.

It operates strictly within 4.5–5.5 V supply range and supports standard TTL input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), with output drive capability of −0.4 mA (source) and 8 mA (sink) under defined load conditions (CL = 50 pF, RL = 500 Ω).

Key Specifications

Pinout & Package

DM74ALS133MX is available at Aetrix Electronics and suitable for industrial control logic, test equipment signal conditioning, and legacy system logic retrofit requiring stable component supply and long-term obsolescence management.

Supply support for DM74ALS133MX includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Fairchild Semiconductor was a U.S.-based semiconductor company specializing in analog and mixed-signal ICs, power management, and logic families before its acquisition by ON Semiconductor in 2016.

The DM74ALS133MX belongs to the advanced low-power Schottky (ALS) TTL logic family, designed for high-speed, low-power digital control in industrial and instrumentation systems where reliability and timing consistency are critical.

FAQ

What logic function does the DM74ALS133MX implement?

The DM74ALS133MX implements a single 13-input NAND gate: output Y is LOW only when all inputs A through M are HIGH; otherwise, Y is HIGH. This function is fully defined in the device's truth table and confirmed across its entire operating range (0°C to +70°C, VCC = 4.5–5.5 V). The DM74ALS133MX delivers deterministic logic behavior with no internal latching or state retention.

Is the DM74ALS133MX pin-compatible with other 74-series 13-input NAND gates?

Yes - the DM74ALS133MX is functionally and pin-for-pin compatible with 74S133 and 74LS133 devices in the same SOIC-16 package. Its pinout matches JEDEC MS-012 layout: inputs A–M on pins 1–13, output Y on pin 14, VCC on pin 16, and GND on pin 8. No PCB redesign is needed when upgrading from those legacy variants to the DM74ALS133MX.

What are the absolute maximum ratings for the DM74ALS133MX?

The DM74ALS133MX has an absolute maximum supply voltage of 7 V, input voltage limit of 7 V, operating free-air temperature range of 0°C to +70°C, and storage temperature range of −65°C to +150°C. Exceeding these values may cause permanent damage. These limits are distinct from recommended operating conditions (VCC = 4.5–5.5 V, TA = 0–70°C), under which all electrical specifications for the DM74ALS133MX are guaranteed.

Does the DM74ALS133MX support open-collector operation?

No - the DM74ALS133MX features a standard totem-pole output stage, not open-collector. Its output can actively drive HIGH (up to −0.4 mA source) and LOW (up to 8 mA sink), eliminating need for external pull-ups in most TTL interfacing. This differs from open-collector variants like DM74ALS133N-OC (not offered); the DM74ALS133MX output is fully buffered and rail-to-rail within its specified VOH/VOL limits.

What thermal characteristics apply to the DM74ALS133MX package?

As a SOIC-16 device (JEDEC MS-012, 0.150" narrow), the DM74ALS133MX has a typical junction-to-ambient thermal resistance (θJA) of 111.0°C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad on a single-layer board; actual thermal performance improves with enhanced PCB copper area or multilayer thermal vias. The DM74ALS133MX does not require heatsinking in typical 5 V, low-duty-cycle logic applications.
