DESCRIPTION
The DG2018 and DG2019 are low voltage, single supply analog switches. The DG2018 is a dual double-pole/double-throw (DPDT) with two control inputs that each controls a pair of single-pole/double-throw (SPDT). The DG2019 uses one control pin to operate four independent SPDT switches. When operated on a +3-V supply, the DG2018's control pins are compatible with 1.8-V digital logic. The DG2019 has an available feature of a VL pin that allows a 1.0-V threshold for the control pin when VL is powered with 1.5 V. Built on Vishay Siliconix's low voltage submicron CMOS process, the DG2018 and DG2019 are ideal for high performance switching of analog signals; providing low on-resistance (6 W @ +2.7 V), fast speed (Ton, Toff @ 42 ns and 16 ns), and a bandwidth that exceeds 150 MHz. The DG2018 and DG2019 were 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.
