M74HC151RM13TR

Overview

The M74HC151RM13TR is an 8-channel multiplexer manufactured by STMicroelectronics using silicon gate C2MOS technology. It provides a single package solution to select one bit of data from up to eight sources. The device features complementary outputs Y and W, with selection determined by address inputs A, B, and C. Functional operation requires the strobe input to be low; when high, the W output is forced high and Y goes low. All inputs include protection circuits against static discharge and transient excess voltage.

Feature Summary

• High-speed CMOS logic fabricated with silicon gate C2MOS technology
• Provides universal function generation capability for four variables
• Features symmetrical output impedance and balanced propagation delays
• Includes built-in protection circuits against static discharge and transient excess voltage

Applications

• Data routing in digital systems
• Universal function generator implementation
• Signal selection in electronic circuits

Procurement Notes

Verify that the component matches the exact manufacturer part number M74HC151RM13TR. Confirm the package type corresponds to SOP-16 as specified in the datasheet. Ensure the revision level aligns with the July 2001 documentation provided. Cross-reference the ordering code to confirm it represents the tape and reel variant rather than tube packaging.

Selection Notes

Select this component when an 8-to-1 multiplexing function is required within a standard 74HC series logic family. Consider its wide operating voltage range of 2V to 6V for compatibility with various supply rails. Evaluate the propagation delay specifications relative to the system clock speed requirements. Verify that the surface-mount SOP-16 package fits the available PCB footprint constraints.

Part Context

This component belongs to the M74HC151 series of high-speed CMOS logic devices. It is pin and function compatible with the standard 74 series 151 multiplexer. The RM13 suffix indicates the specific tape and reel packaging format used for automated assembly processes.

Replacement Considerations

Direct replacements must maintain 8-channel multiplexing functionality and 74HC logic compatibility. Verify that any substitute supports the same 2V to 6V operating voltage range and SOP-16 package dimensions.
