DESCRIPTION

The DG611, DG612, DG613 feature high-speed lowcapacitance

lateral DMOS switches. Charge injection has

been minimized to optimize performance in fast sample-andhold

applications.

Each switch conducts equally well in both directions when on

and blocks up to 16 Vp-p when off. Capacitances have been

minimized to ensure fast switching and low-glitch energy. To

achieve such fast and clean switching performance, the

DG611, DG612, DG613 are built on the Vishay Siliconix

proprietary D/CMOS process. This process combines

n-channel DMOS switching FETs with low-power CMOS

control logic and drivers. An epitaxial layer prevents latchup.

The DG611 and DG612 differ only in that they respond to

opposite logic levels. The versatile DG613 has two normally

open and two normally closed switches. It can be given

various configurations, including four SPST, two SPDT, one

DPDT.
