DESCRIPTION
The
DG641,
DG642,
DG643
are
high
performance
monolithic video switches designed for switching wide
bandwidth analog and digital signals. DG641 is a quad
SPST, DG642 is a single SPDT, and DG643 is a dual SPDT
function.
These
devices
have
exceptionally
low
on-resistances (5
typ-DG642), low capacitance and high
current handling capability.
To achieve TTL compatibility, low channel capacitances and
fast switching times, the DG641, DG642, DG643 are built on
the Vishay Siliconix proprietary D/CMOS process. Each
switch conducts equally well in both directions when on, and
blocks up to 14 Vp-p when off. An epitaxial layer prevents
latchup.
