SN74HC153AN

Overview

The SN74HC153AN is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates on a single power supply with a voltage range of 2V to 6V. The device features two independent multiplexers, each selecting one of four data inputs based on binary address inputs. It utilizes a 16-pin DIP (Dual In-Line Package) for through-hole mounting. The component supports output currents of 7.8mA for both high and low states. It functions within an operating temperature range of -40°C to 85°C and belongs to the 74HC series logic family.

Feature Summary

• Integrates two independent 4-to-1 multiplexers within a single package
• Provides full binary decoding for input selection via common address lines
• Operates effectively across a wide supply voltage range from 2V to 6V
• Supports surface-mount or through-hole integration depending on specific package variant

Applications

• Data routing in digital communication systems
• Address decoding for memory access
• Waveform generation circuits
• Parallel-to-serial data conversion

Procurement Notes

Verify the exact suffix 'AN' against official Texas Instruments documentation to confirm pinout and package dimensions, as variations exist between SOIC and DIP formats. Ensure compatibility with existing PCB footprints and verify RoHS compliance status for the specific manufacturing batch before procurement.

Selection Notes

Select this component when dual independent data selection is required within a single logic gate footprint. Consider the 74HC series speed and voltage characteristics relative to system requirements. Verify that the 16-pin DIP package aligns with assembly methods and board space constraints compared to alternative surface-mount options.

Part Context

This part belongs to the widely used 74HC logic family, known for high-speed CMOS operation compatible with TTL levels. The 74HC153 specifically addresses applications requiring multiple data paths to be managed efficiently. It serves as a fundamental building block in complex digital designs involving signal switching and data management tasks.

Replacement Considerations

Check for direct equivalents such as SN74HC153N or SN74HC153D if package availability differs. Verify functional compatibility with other 74HC153 variants from different manufacturers, ensuring pinouts and electrical specifications match exactly.
