DM74ALS153SJX

Overview

The DM74ALS153SJX is a dual 4-input multiplexer manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and supports a single power supply configuration. The device features two independent circuits, each selecting one of four data inputs based on address lines. It is housed in a 16-SOP surface-mount package with dimensions of 0.209 inches (5.30mm) width. The component is designed for commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Dual independent 4-to-1 multiplexing functionality
• Advanced Low-power Schottky (ALS) technology implementation
• Surface-mount 16-SOP packaging format

Applications

• Data routing in digital logic systems
• Signal selection in microprocessor interfaces
• Address decoding applications

Procurement Notes

Verify the manufacturer designation carefully, as this part was originally produced by Fairchild Semiconductor before its semiconductor business became onsemi. Confirm the specific suffix SJX corresponds to the 16-SOP package type. Check current availability status as the component may be discontinued or subject to lifecycle changes.

Selection Notes

Select this component when dual 4:1 multiplexing is required in space-constrained designs utilizing surface-mount technology. Ensure the system operates within the specified 4.5V to 5.5V voltage range. Consider the ALS series performance characteristics regarding speed and power consumption relative to other logic families.

Part Context

This device belongs to the 74ALS logic family, known for improved speed and lower power consumption compared to standard TTL. The DM74ALS153SJX specifically provides two separate multiplexers in a compact surface-mount package, suitable for modern electronic assemblies requiring efficient signal routing.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include SN74ALS153NSR and SN74AS153NSR from Texas Instruments.
