The two independent circuits each handle a 4:1 mux, so a single 16-SOIC package can serve two separate data paths or combine into an 8:1 mux with a chip-select. ## Board-level fit and temperature range Housed in a 16-SOIC (0.154\", 3.90mm width) surface-mount package, the SN74HC253D sits on a standard SOIC footprint with 1.27mm pitch — no fine-pitch rework required. Single-supply operation simplifies the power rail: just one 2V to 6V net, no split supplies or level-shifting for the mux core. The independent circuit count of 1 means both mux channels share the same address lines but have separate output-enable controls.","metaTitle":"SN74HC253D TI 74HC Dual 4:1 Multiplexer, 16-SOIC","metaDescription":"Texas Instruments SN74HC253D dual 4:1 multiplexer, 74HC family, 2V to 6V supply, 7.8mA output, -40°C to 85°C, 16-SOIC.
