DG2741, DG2742, DG2743
Vishay Siliconix
Low-Voltage, 0.8 RON, Dual SPST Analog Switch
DESCRIPTION
FEATURES
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.

Notes:
a. Room = 25 °C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, nor subjected to production test.
e. VIN = input voltage to perform proper function.
f. Guaranteed by 3 V leakage testing, not production tested.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
