3 Description
The TMUX9612 is a modern high voltage capable
analog switch with Latch-Up immunity. Each device
has four independently controllable 1:1, single-pole
single-throw (SPST) switch channels. The device
works well with dual supplies, a single supply, or
asymmetric supplies up to a maximum supply voltage
of 220V. The TMUX9612 device provides consistent
analog parametric performance across the entire
supply voltage range. The device also supports
bidirectional analog and digital signals on the source
(Sx) and drain (Dx) pins.
All logic inputs support logic levels of 1.8V, 3.3V, and
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 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.
