CD74HC153M

Signal Switches, Multiplexers, Decoders Overview

The CD74HC153M is a dual 4-line to 1-line data selector/multiplexer manufactured by Harris Corporation. It belongs to the HC/UH series of high-speed CMOS logic devices and is housed in a 16-pin Small Outline Package (SOP). The integrated circuit contains two independent multiplexers, each featuring four data inputs, two enable inputs, and one true output. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to 125°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual independent multiplexer architecture providing two separate 4-to-1 data selection channels

• Wide operating voltage capability supporting systems ranging from 2V to 6V
• Industrial-grade thermal stability allowing operation across extended temperature ranges

Signal Switches, Multiplexers, Decoders Applications

• Data routing and signal selection in digital communication systems
• Address decoding for memory and I/O port selection
• Waveform generation and pulse width modulation circuits
• Parallel-to-serial data conversion interfaces

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through official manufacturer documentation or authorized distributors. Confirm package marking matches the SOP-16 specification. Check RoHS compliance status as indicated in datasheets, noting potential variations between original Harris production and subsequent licensees. Ensure storage conditions prevent moisture damage to the plastic epoxy body.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required within a single package. The HC series offers speed and power characteristics suitable for general-purpose logic applications. Verify that the 16-pin SOP footprint aligns with the target PCB design. Consider the wide voltage range if the system requires flexibility between 2V and 6V operation levels.

Signal Switches, Multiplexers, Decoders Part Context

This device is part of the standard 74HC logic family, widely used for general-purpose digital switching. Harris Corporation originally developed these components before intellectual property transitions often occurred to other semiconductor manufacturers like Texas Instruments. The CD74HC153M represents a specific variant optimized for surface-mount assembly using the narrow-body SOP package.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Equivalent parts include SN74HC153 from Texas Instruments and MC74HC153 from ON Semiconductor. Verify pinout compatibility and electrical specifications such as propagation delay and output drive current before substitution.
