SN74ALS153NS

Overview

The SN74ALS153NS is a dual 1-of-4 data selector/multiplexer from the Texas Instruments ALS logic family. 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 features a propagation delay of 9 ns at 5V and 25°C, with low-level output current capability of 8 mA and high-level output current of -400 uA. Packaged in a 16-pin SOIC format, it integrates two independent multiplexers for signal routing applications.

Feature Summary

• Integrates two independent 4-line to 1-line data selectors within a single package
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption
• Provides standard TTL-compatible input and output levels for direct interfacing

Applications

• Data routing in digital communication systems
• Address decoding circuits
• Signal selection in microprocessor-based systems

Procurement Notes

Verify the specific suffix 'NS' confirms the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure the ordering part number matches the required package style and temperature grade specifications exactly.

Selection Notes

Select this component when dual independent multiplexing functionality is required in space-constrained designs. The ALS series offers a balance between speed and power dissipation suitable for general-purpose logic applications. Verify that the 16-pin SOIC footprint aligns with the target PCB layout constraints and thermal management requirements.

Part Context

This component belongs to the SN74ALS153 series, which includes variants such as SN74ALS153N and SN74ALS157ANSR. These devices share the same logical family characteristics but differ in pin counts and internal circuit configurations. The SN74ALS153NS specifically denotes the surface-mount SOIC version of the dual multiplexer.

Replacement Considerations

SN74ALS153N is a verified equivalent part number representing the same functional device in a different package configuration.
