DESCRIPTION
The DG381B–DG390B series of monolithic CMOS analog
switches was designed for applications in instrumentation,
communications, and process control. This series is suited for
applications requiring fast switching and nearly flat
on-resistance over the entire voltage range.
switches are ideal for battery powered applications, without
sacrificing switching speed. Break-before-make switching
action is guaranteed, and an epitaxial layer prevents latchup.
Single supply operation is allowed by connecting the V– rail to
0 V.
Designed on Vishay Siliconix’ PLUS-40 CMOS process,
these devices achieve low power consumption (3.5 mW
typical) and excellent on/off switch performance. These
Each switch conducts equally well in both directions when on,
and blocks up to the supply voltage when off. These switches
are CMOS and quasi TTL logic compatible.

a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25_C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
