SN74HC153DR

Overview

The SN74HC153DR is a dual 4-line-to-1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 16-SOIC package. The device features two independent multiplexing circuits, each selecting one of four data inputs based on address lines. It functions across an industrial temperature range of -40°C to +85°C with output drive capabilities of 7.8mA for both high and low states.

Feature Summary

• Dual independent 4-to-1 multiplexing architecture
• Wide single-supply voltage operation from 2V to 6V
• Industrial-grade thermal stability for harsh environments

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor interfaces
• Signal selection in measurement instrumentation

Procurement Notes

Verify the specific suffix 'DR' against the manufacturer's current datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the ordering information with official Texas Instruments documentation to validate availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when dual independent signal routing is required within a compact surface-mount footprint. The HC logic family offers compatibility with standard CMOS levels while providing sufficient drive current for moderate loads. Consider the 16-SOIC package dimensions for PCB layout constraints and verify that the operating voltage range aligns with the system power supply rails.

Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices produced by Texas Instruments. The 74HC153 specifically implements dual 4-input multiplexer functionality. It is designed for applications requiring efficient data path switching with low power consumption and wide voltage flexibility compared to older logic families.

Replacement Considerations

Compatible alternatives include the SN74HC153PWR (TSSOP package) and SN74HC153NS (SOIC package). Verify pinout compatibility and electrical characteristics before substitution.
