MC74F151M

Signal Switches, Multiplexers, Decoders Overview

The MC74F151M is an 8-input multiplexer belonging to the onsemi F/FAST logic series. It features a single function with eight data input lines and one primary output line, complemented by a complementary output. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a 16-lead Small Outline (SOIC) surface-mount package. The component supports through-hole or surface-mount installation styles depending on specific variant configurations, though the M suffix typically denotes SOIC. It functions as a high-speed data selector.
