DG2018, DG2019
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 V_L pin that allows a 1.0 V threshold for
the control pin when V_L 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 (T_on, T_off 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.
