DESCRIPTION
The DG441B/442B are monolithic quad analog switches
designed to provide high speed, low error switching of analog
and audio signals. The DG441B/442B are upgrades to the
original DG441/442.
been minimized on the drain for use in sample-and-hold
circuits.
The DG441B/442B are built using Vishay Siliconix’s
high-voltage silicon-gate process. An epitaxial layer prevents
latchup.
Combing low on-resistance (45 ꢀ, typ.) with high speed
(tON 120 ns, typ.), the DG441B/442B are ideally suited for
Data Acquisition, Communication Systems, Automatic Test
Equipment, or Medical Instrumentation. Charge injection has
When on, each switch conducts equally well in both directions
and blocks input voltages to the supply levels when off.
