3 Description
The MUX808-Q1 and MUX809-Q1 are modern high
voltage capable analog multiplexers in 8:1 (single
ended) and 4:1 (differential) configurations. The
devices work well with dual supplies, a single supply,
or asymmetric supplies up to a maximum supply
voltage of 100V. The MUX80x-Q1 devices provide
consistent analog parametric performance across the
entire supply voltage range. The MUX808-Q1 and
MUX809-Q1 support bidirectional analog and digital
signals on the source (Sx) and drain (Dx) pins.
All logic inputs support logic levels of 1.8V, 3.3V, 5V
and can be connected as high as 48V, allowing for
system flexibility with control signal voltage. Fail-safe
logic circuitry allows voltages on the logic pins to be
applied before the supply pin, protecting the device
from potential damage.
The device family provides latch-up immunity,
preventing undesirable high current events between
parasitic structures within the device. A latch-up
condition typically continues until the power supply
rails are turned off and can lead to device failure.
The latch-up immunity feature allows this family of
multiplexers to be used in harsh environments.
