It selects one of eight data sources based on a three-bit address input, with a strobe input for enabling or disabling the output. The 2V to 6V single-supply range makes it compatible with 3.3V and 5V logic rails common in industrial control, sensor interface, and data-acquisition boards. The 16-TSSOP package (4.40 mm width) suits dense surface-mount layouts where board area is constrained.
Output drive is specified at 7.8 mA high and low — enough to drive a single CMOS load or a low-power LED indicator, but not a long cable or high-fanout bus without buffering.
