onsemi 20-SOIC MM74C244WM

The part number MM74C244WM refers to a 74C244, which is a quad 3-state non-inverting buffer device from the 7400 series logic family. This IC typically contains four independent buffers with three-state outputs, allowing them to be connected to buses and controlled for high-impedance (high-Z) states. Each buffer has two input lines and one output line that reproduces the logical state of the inputs while in an active state. It's commonly used for driving higher loads or isolating circuits without affecting their logical levels. Specifications and dimensions such as package type and unit weight are available in its datasheet for detailed implementation.
