DG2018, DG2019  
Vishay Siliconix  
Low Voltage, Dual DPDT and Quad SPDT Analog Switches  
DESCRIPTION  
FEATURES  
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.  
Low voltage operation (1.8 V to 5.5 V)  
Low on resistance  
- RDS(on): 6 Ω at 2.7 V  
Low voltage logic compatible  
- DG2019: VINH = 1 V  
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.  
High bandwidth: 180 MHz  
QFN-16 package  
BENEFITS  
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.  
Ideal for both analog and digital signal switching  
Reduced power consumption  
High accuracy  
Reduced PCB space  
Fast switching  
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.  
Low leakage  
APPLICATIONS  
Cellular phones  
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.  
Audio and video signal routing  
PCMCIA cards  
Battery operated systems  
Portable instrumentation
