SN74LS153DR

Overview

The SN74LS153DR is a dual 1-of-4 data selector/multiplexer manufactured by Texas Instruments. It integrates two independent multiplexers within a single 16-pin SOIC package. Each multiplexer selects one of four data inputs based on binary address signals and routes it to a common output. The device operates with a standard supply voltage range of 4.75V to 5.25V. It supports an operating temperature range from 0°C to +70°C, suitable for commercial applications.

Feature Summary

• Integrates two independent 4-line to 1-line data selectors in a single package
• Provides complete binary decoding for input selection
• Features separate strobe (enable) inputs for each multiplexer section
• Offers high fan-out capability with low-impedance totem-pole outputs

Applications

• Data routing and selection in digital logic circuits
• Parallel-to-serial data conversion systems
• Implementation of combinational logic functions
• Cascading configurations for expanded N-line to N-line selection

Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format and SOIC-16 physical dimensions. Confirm the 'LS' designation aligns with Low-power Schottky TTL requirements for your target voltage and speed specifications. Ensure the commercial temperature grade meets your environmental constraints.

Selection Notes

Select this component when dual independent multiplexing is required within a compact footprint. The LS series offers compatibility with standard TTL logic families while providing improved power consumption characteristics compared to standard LS devices. Verify that the propagation delay and drive current meet the timing requirements of the downstream circuitry.

Part Context

This part belongs to the Texas Instruments 74LS family of logic integrated circuits. The 74LS153 variant specifically provides dual multiplexer functionality. It is designed for general-purpose digital applications requiring reliable data switching and selection capabilities within standard commercial temperature ranges.

Replacement Considerations

Compatible substitutes include SN74LS153N (DIP package) or equivalent parts from other manufacturers such as MC74LS153 or HD74LS153, provided pinout and electrical specifications remain identical.
