SN74LS298N

Overview

The SN74LS298N is a quadruple 2-input multiplexer with storage, belonging to the Texas Instruments 74LS series. It integrates four independent multiplexers, each featuring two data inputs, a select input, and a storage register. The device utilizes Low-Power Schottky (LS) TTL technology, ensuring high-speed operation with reduced power consumption. It operates within a standard voltage range of 4.75V to 5.25V and supports through-hole mounting in a 16-pin PDIP package.

Feature Summary

• Integrates four independent 2-to-1 multiplexers with dedicated storage registers for each channel.
• Utilizes Low-Power Schottky (LS) logic technology to balance switching speed with energy efficiency.
• Provides true output signals directly from the multiplexer stage before storage registration.

Applications

• Data routing systems requiring temporary storage of selected signal paths.
• Digital logic circuits implementing sequential selection operations.
• Interface modules connecting multiple low-speed data sources to a single processing line.

Procurement Notes

Verify the manufacturer marking matches Texas Instruments specifications. Confirm the package type is 16-pin PDIP and the logic family is LS. Ensure the part number suffix indicates the correct variant for your application requirements.

Selection Notes

Select this component when designing circuits that require simultaneous multiplexing and latching of four separate data lines. Consider the LS series characteristics for compatibility with existing TTL logic families in legacy or industrial control systems.

Part Context

This component is part of the broader 74LS logic family, widely used in digital electronics for its reliability and standard pinouts. It serves as a specialized interface between combinational logic and sequential storage elements, facilitating complex data handling tasks in microprocessor-based systems.
