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

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 compatible

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.
