It is a high-speed CMOS dual bilateral switch fabricated with silicon gate CMOS technology. It consists of four independent high-speed switches capable of controlling either digital or analogue signals while maintaining the CMOS low power dissipation. Control input (C) is provided to control the switch. The switch turns ON while the C input is high, and the switch turns OFF while low. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
