DESCRIPTION  
The DG2018 and DG2019 are low voltage, single supply  
analog switches. The DG2018 is 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.  
performance switching of analog signals; providing low  
on-resistance (6 W @ +2.7 V), fast speed (Ton, Toff @ 42 ns  
and 16 ns), and a bandwidth that exceeds 150 MHz.  
a
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.  
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.  
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.  
Built on Vishay Siliconix’s low voltage submicron CMOS  
process, the DG2018 and DG2019 are ideal for high
