Description
The DG211 and DG212 are low cost quad single-pole
single-throw analog switches for use in general purpose
switching applications in communication, instrumentation
and process control. These devices differ only in that the
digital control logic is inverted (see Truth Table). The use
of both p- and n-channel devices minimizes on-resistance
variation over the analog signal range.
voltage rating of 40 V, both switches will handle "15-V
input signals with ease, and have a continuous current
rating of 20 mA. An epitaxial layer prevents latchup.
Designed with the Siliconix PLUS-40 CMOS process to
combine low power dissipation with a high breakdown
For new designs we recommend the silicon-gate
DG211B/212B upgrades.
Both devices feature true bi-directional performance
(with no offset voltage) in the on condition, and will block
signals to 30 V peak-to-peak in the off condition.
