DG441, DG442
Vishay Siliconix
Quad SPST CMOS Analog Switches
DESCRIPTION
The DG441, DG442 monolithic quad analog switches are
designed to provide high speed, low error switching of analog
and audio signals. The DG441 has a normally closed
function. The DG442 has a normally open function.
Combining low on-resistance (50 , typ.) with high speed
(tON 150 ns, typ.), the DG441, DG442 are ideally suited for
upgrading DG201A/202 sockets. Charge injection has been
minimized on the drain for use in sample-and-hold circuits.
To achieve high voltage ratings and superior switching
performance, the DG441, DG442 are built on Vishay
Siliconix’s high-voltage silicon-gate process. An epitaxial
layer prevents latchup.
Each switch conducts equally well in both directions when
on, and blocks input voltages to the supply levels when off.
