The DG2018 is low voltage, single supply analog switches. The DG2018 is a dual double-pole/doublethrow (DPDT) with two control inputs that each controls a pair of single-pole/double-throw (SPDT).When operated on a + 3 V supply, the DG2018’s control pins are compatible with 1.8 V digital logic.Built on Vishay Siliconix’s low voltage submicron CMOS process, the DG2018 is ideal for high performance switching of analog signals; providing low onresistance (6 O at + 2.7 V), fast speed (Ton, Toff at 42 ns and 16 ns), and a bandwidth that exceeds 180 MHz.The DG2018 is designed to offer solutions that extend beyond audio/video functions, to providing the performance required for today’s demanding mixed-signal switching in portable applications.An epitaxial layer prevents latch-up. Brake-before-make is guaranteed for all SPDT’s. All switches conduct equally well in both directions when on, and blocks up to the power supply level when off.
