Vishay Siliconix
Low Voltage, Dual DPDT and Quad SPDT Analog Switches
DESCRIPTION
The DG2018 and DG2019 are low voltage, single supply
analog switches. The DG2018 is a dual double-pole/double-
throw (DPDT) with two control inputs that each controls a
pair of single-pole/double-throw (SPDT). The DG2019 uses
one control pin to operate four independent SPDT switches.
When operated on a + 3 V supply, the DG2018’s control pins
are compatible with 1.8 V digital logic. The DG2019 has an
available feature of a VL pin that allows a 1.0 V threshold for
the control pin when VL is powered with 1.5 V.
Built on Vishay Siliconix’s low voltage submicron CMOS
process, the DG2018 and DG2019 are ideal for high
performance switching of analog signals; providing low on-
resistance (6 Ω at + 2.7 V), fast speed (Ton, Toff at 42 ns and
16 ns), and a bandwidth that exceeds 180 MHz.
The DG2018 and DG2019 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.
An epitaxial layer prevents latch-up. Brake-before-make is
guaranteed for all SPDT’s. All switches conduct equally well
in both directions when on, and blocks up to the power
supply level when off.
