DESCRIPTION
The DG2741/2742/2743 are low voltage, single supply, dual SPST analog switches. Designed for high performance switching of analog signals, the DG2741/2742/2743 provide low on-resistance (0.8 Ω @ +2.7 V), fast speed (t ON, t OFF @ 35 ns and 33 ns) and the ability to handle signals over the entire analog voltage range. When operated on a +3-V supply, control pins are patible with 1.8-V digital logic. Additionally,on-resistance flatness and matching (0.18 Ω and 0.08 Ω, respectively) offer high accuracy between channels. The DG2741 contains two normally open (NO) switches, the DG2742 contains two normally closed (NC) switches, and the DG2743 contains one normally open and one normally closed switch. Break-before-make is guaranteed.
Built on Vishay Siliconix’s low voltage submicron CMOS process, the DG2741/2742/2743 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.
