onsemi 20-SOIC 74F244SC

The 74F244SC is a high-speed CMOS variant of the 74LS244, which is an 8-bit bidirectional buffer/line driver. It's designed to improve signal integrity and support high-speed data transfer in digital circuits while maintaining low power consumption. This device has three-state outputs, enabling it to connect multiple bus systems together with controlled signal direction for each output. It's commonly used for memory address driving, interface buffering, and general-purpose I/O expansion.
