DG2741, DG2742, DG2743
Vishay Siliconix
Low-Voltage, 0.8  R_ON, Dual SPST Analog Switch
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 (t_ON, t_OFF 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, on-
resistance 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.
