DESCRIPTION
The DG611/612/613 feature high-speed low-capacitance
lateral DMOS switches. Charge injection has been minimized
to optimize performance in fast sample-and-hold 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
DG611/612/613 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.
