CD74HC157M96

Overview

The CD74HC157M96 is a high-speed CMOS quad 2-input multiplexer manufactured by Harris Corporation. It features four independent multiplexers, each selecting one of two data inputs based on a common select line. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to 125°C. It utilizes a 16-pin Small Outline Package (SOP) with a lead pitch of 0.25 inches. The logic series is HC/UH, and the output polarity is true.

Feature Summary

• Contains four independent 2-to-1 multiplexing circuits
• Common select input controls all four channels simultaneously
• High-speed CMOS technology for low power consumption
• Wide operating voltage and temperature ranges

Applications

• Data routing in digital systems
• Signal selection in measurement equipment
• Address decoding applications

Procurement Notes

Verify component authenticity as this part may be sourced from secondary markets or surplus distributors. Confirm the manufacturer marking corresponds to Harris Corporation or its successors. Check for RoHS compliance status, as original Harris parts often do not meet current environmental regulations. Ensure the package condition matches the specified SOP-16 form factor before integration into designs requiring strict dimensional tolerances.

Selection Notes

Select this component when multiple independent signal paths require simultaneous switching controlled by a single address line. The HC series offers compatibility with standard TTL logic levels while maintaining CMOS noise immunity. Consider the wide temperature range if the application involves harsh industrial environments. Verify that the 16-pin SOP footprint aligns with the target PCB layout constraints.

Part Context

This component belongs to the CD74HC15x family of multiplexers produced by Harris Corporation, which was later acquired by Texas Instruments. The 'M96' suffix typically denotes a specific tape-and-reel packaging variant or manufacturing code associated with Harris's surface-mount production lines. It represents a legacy high-performance logic solution prior to industry-wide standardization under TI branding.
