CD74HCT153M

Overview

The CD74HCT153M is a high-speed CMOS logic device belonging to the HCT series, manufactured by Harris Corporation. It functions as a dual 4-input multiplexer with true outputs, packaged in a 16-pin Small Outline (SOP) format. The component operates on a single power supply within a voltage range of 4.5V to 5.5V. It supports an operating temperature range from -55°C to 125°C and features a load capacitance of 50 pF.

Feature Summary

• Dual independent 4-to-1 multiplexing functionality
• High-speed CMOS technology compatible with TTL logic levels
• True output polarity for direct signal routing

Applications

• Data selection and routing in digital systems
• Signal path switching in communication equipment
• Address decoding in memory architectures

Procurement Notes

Verify the manufacturer origin, as Texas Instruments has acquired Harris Corporation's logic business. Confirm RoHS compliance status, as original Harris versions may not meet current environmental standards. Check for obsolete status or end-of-life notices from current distributors. Ensure the SOP16 package matches your PCB footprint requirements.

Selection Notes

Select this component when dual 4:1 multiplexing is required with HCT logic compatibility. It serves as a suitable alternative to standard 74HC153 devices where specific Harris manufacturing characteristics are needed. Consider the wide industrial temperature range (-55°C to 125°C) for harsh environment applications. Verify pinout compatibility if replacing similar multiplexers in existing designs.

Part Context

This part belongs to the CD74HCTxxxyy series, which defines high-speed CMOS logic with TTL-compatible inputs. The '153' designation specifically indicates a dual 4-input multiplexer configuration. The 'M' suffix denotes the 16-pin Small Outline Package. This series was originally produced by Harris Corporation before its semiconductor assets were transferred to other manufacturers.

FAQ

What is the output type of the CD74HCT153M?

The device provides true outputs, meaning the selected input signal appears at the output without inversion.

Is the CD74HCT153M RoHS compliant?

Original Harris Corporation versions of this part are generally not RoHS compliant. Later equivalents like the CD74HCT153MG4 are compliant.
