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 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.
