DESCRIPTION

The DG2741, DG2742, DG2743 are low voltage, single

supply, dual SPST analog switches. Designed for high

performance switching of analog signals, the DG2741,

DG2742, DG2743 provide low on-resistance (0.8 ? at

+ 2.7 V), fast speed (tON, tOFF at 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, onresistance

flatness and matching (0.18 ? and 0.08 ?,

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, DG2742, DG2743 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.
