SN74ALS133N

Overview

The SN74ALS133N is a 13-input positive-NAND gate from the Texas Instruments ALS logic family, housed in a 16-pin PDIP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device provides a low-level output current of up to 8 mA and a high-level output current of -0.4 mA. Propagation delays are specified between 3 ns and 16 ns for low-to-high transitions, and 5 ns to 25 ns for high-to-low transitions under standard load conditions.

Feature Summary

• Implements a single 13-input positive-NAND logic function
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance
• Provides robust low-level output drive capability

Applications

• Digital logic circuits requiring complex input decoding
• Microprocessor-based system address decoding
• Control logic for multi-state digital systems

Procurement Notes

Verify that the specific orderable part number matches the required package type, as the SN74ALS133 series includes SOIC and SOP variants alongside the PDIP option. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum. Ensure the selected variant aligns with the intended manufacturing process and environmental requirements.

Selection Notes

Select this component when a single gate with thirteen inputs is necessary for Boolean NAND operations. The ALS series offers a balance of speed and power consumption suitable for general-purpose digital applications. Consider alternative packages if surface-mount assembly is preferred over through-hole mounting.

Part Context

This device belongs to the SN54/74ALS133 family of 13-input positive-NAND gates. While the SN54 version supports military temperature ranges, the SN74 variant is rated for commercial temperatures. The family includes various packaging options such as ceramic chip carriers and plastic small-outline packages to accommodate different board layout constraints.

Replacement Considerations

SN74ALS133DR and SN74ALS133NSR are parameter-equivalent alternatives within the same product family.
