DM74ALS133MX

Inverter Gates Overview

The DM74ALS133MX is a single 13-input NAND gate from the Advanced Low-power Schottky (ALS) logic family, manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 25 ns at 5 V with a 50 pF load. The device provides a low-level output current of 8 mA and a high-level output current of -400 µA. It is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package and supports surface-mount installation. The component is rated for an operating temperature range of 0°C to +70°C.

Inverter Gates Feature Summary

• Performs the logic NAND function using 13 inputs and a single output channel.
• Guarantees switching specifications over the full operating temperature range and supply voltage variations.
• Utilizes Advanced Low-power Schottky technology for improved AC performance compared to standard LS series devices.

Inverter Gates Applications

• Digital logic circuits requiring complex input decoding
• Microprocessor system address decoding
• Control logic for data bus management

Inverter Gates Procurement Notes

Verify the specific ordering suffix and manufacturer origin, as this part number has been produced by multiple entities including Fairchild Semiconductor and onsemi. Confirm RoHS compliance status and lead-free markings if required for assembly processes. Check for obsolescence notices or end-of-life notifications, as availability may be limited. Ensure the package type matches the design footprint requirements before procurement.

Inverter Gates Selection Notes

Select this component when a high-fan-in NAND gate is required for signal processing in industrial or commercial environments. The ALS series offers a balance between speed and power consumption suitable for general-purpose digital applications. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the 13-input requirement aligns with the circuit design to avoid unused input handling issues.

Inverter Gates Part Context

This device belongs to the DM74ALS133 series, which includes variants such as the DM74ALS133M and DM74ALS133N. These parts share identical logical functionality but differ in packaging options, including SOIC and PDIP formats. The series is part of the broader 74ALS logic family, designed to replace older TTL components with faster switching speeds and lower power dissipation characteristics.
