MC74ACT151M

Overview

The MC74ACT151M is an 8-input digital multiplexer manufactured by onsemi, belonging to the 74ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides both true and complementary outputs capable of sourcing and sinking 24 mA. It is housed in a 16-pin SOIC package and supports synchronous operation with positive edge triggering.

Feature Summary

• Provides high-speed selection of one data line from eight sources
• Features TTL-compatible input logic levels for direct interfacing
• Delivers balanced propagation delay with strong output drive capability

Applications

• Universal function generator for logic functions of four variables
• Parallel-to-serial data conversion
• Data selector circuits

Procurement Notes

Verify the specific suffix 'M' against the official datasheet to confirm package type and temperature grade. Ensure compatibility with 5V systems due to ACT series requirements. Check RoHS compliance status and moisture sensitivity level before integration into production workflows.

Selection Notes

Select this component when an 8-channel multiplexer with TTL-compatible inputs is required. The ACT series offers speed comparable to F-type devices with significantly lower power consumption. Verify that the 24 mA output current meets load requirements and that the 16-pin SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the 74ACT family of CMOS logic integrated circuits. It serves as a standard solution for data routing applications requiring high speed and low power. The device is widely used in digital systems where reliable signal selection and buffering are necessary.

Replacement Considerations

Compatible substitutes include CD74ACT151 and 74ACT151SC. Verify pinout compatibility and electrical specifications such as propagation delay and output current before substitution.
