SN74LS298DR

Overview

The SN74LS298DR is a Low-Power Schottky (LS) logic integrated circuit manufactured by Texas Instruments. It features four independent 2-input multiplexers with storage capabilities, housed in a 16-pin SOIC surface-mount package. The device operates on a single 5V supply within the standard range of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent 2-to-1 multiplexer channels with built-in D-type flip-flop storage registers for data retention.

Applications

• Data routing and selection in digital logic circuits
• Parallel-to-serial conversion systems
• Address decoding and control logic

Procurement Notes

Verify that the specific part number matches the required LS series specifications and SOIC-16 package dimensions. Confirm RoHS compliance status as it varies by manufacturing batch and date code. Ensure the supplier provides valid traceability documentation for industrial or commercial deployment.

Selection Notes

Select this component when multiple data streams require selective routing into storage elements within a single chip footprint. It serves as a compact alternative to discrete multiplexer and flip-flop combinations, reducing board space and interconnect complexity in TTL-compatible designs.

Part Context

This device belongs to the Texas Instruments 74LS family, designed for low-power operation while maintaining high-speed switching characteristics. It is functionally compatible with other 74LS series components, allowing seamless integration into existing TTL-based logic architectures without requiring level shifting.

Replacement Considerations

SN74LS298N: Pin-compatible through-hole DIP-16 variant offering identical logical functionality for prototyping or legacy socket applications.
