SN74LS153N

Overview

The SN74LS153N is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It integrates two independent multiplexers within a single PDIP-16 package. Each multiplexer selects one of four data inputs based on binary address signals and routes it to a dedicated output. The device operates using TTL logic standards, featuring true outputs for both channels.

Feature Summary

• Integrates two independent 4-to-1 multiplexing circuits
• Utilizes standard TTL logic technology
• Provides direct routing of selected data inputs to outputs

Applications

• Data routing in digital systems
• Implementation of combinational logic functions
• Address decoding applications

Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics may supply this part number. Confirm the package type matches the required DIP-16 configuration. Ensure the LS series logic family aligns with system voltage and speed requirements before procurement.

Selection Notes

Select this component when dual independent multiplexing is required within a standard TTL environment. The PDIP-16 package suits through-hole prototyping and legacy board designs. Verify that the propagation delay characteristics meet the timing constraints of the target application circuit.

Part Context

This component belongs to the widely used 74LS series of logic integrated circuits. It serves as a fundamental building block for digital signal processing and control logic. The dual configuration allows for efficient space utilization in complex digital designs requiring multiple data selection paths.

Replacement Considerations

Compatible substitutes include SN74LS153 from other manufacturers such as Motorola or National Semiconductor. Equivalent parts like SN74HC153 offer CMOS compatibility but require voltage level verification.
