SN74ALS33ANG4

Overview

The SN74ALS33ANG4 is a quadruple 2-input positive-NOR buffer manufactured by Texas Instruments. It features open-collector outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes the Advanced Low-power Schottky (ALS) logic series, providing high-speed performance with low power consumption. It is housed in a 14-pin Dual In-Line Package (DIP) with a standard 0.300-inch width.

Feature Summary

• Quadruple 2-input NOR gate configuration
• Open-collector output structure
• Advanced Low-power Schottky logic technology

Applications

• Digital logic buffering
• Signal inversion circuits
• General-purpose logic applications

Procurement Notes

Verify component status as this part may be obsolete. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing system requirements before procurement. Check for direct substitutes if original stock is unavailable.

Selection Notes

Select this component for applications requiring quad NOR gates with open-collector outputs. Consider the ALS series for improved speed and power efficiency compared to standard TTL. Verify package compatibility with PCB layout constraints.

Part Context

Part of the Texas Instruments 74ALS logic family. Designed for high-speed digital systems requiring low power dissipation. Open-collector outputs allow for wired-AND connections and level shifting capabilities.

Replacement Considerations

Direct substitute: SN74LS33N. Verify pinout and electrical characteristics match system requirements when transitioning from ALS to LS logic families.
