Product Overview
The SN74F253NS is a dual 4-line to 1-line data selector/multiplexer from Texas Instruments, featuring 3-state outputs. It is designed for high-speed digital systems, offering low power consumption and high noise immunity. The device operates from a 4.5V to 5.5V supply and is available in a 16-pin SO package (NS suffix). Each multiplexer selects one of four data sources, controlled by common select inputs (A and B). The outputs can be independently enabled or disabled via active-low output enable inputs (1G and 2G).
