3 Description
The TMUX113x devices are precision complementary
metal-oxide semiconductor (CMOS) switches with
multiple channels. The TMUX1133 is a 2:1, singlepole
double-throw (SPDT), configuration with three
independently controlled channels and an EN pin
to enable or disable all three switches. The
TMUX1134 contains four independently controlled
SPDT switches. Wide operating supply of 1.08V to
5.5V, or ±2.75V dual supply, allows for use in a
broad array of applications from medical equipment to
industrial systems. The device supports bidirectional
analog and digital signals on the source (Sx) and
drain (Dx) pins ranging from VSS to VDD. For single
supply applications VSS must be connected to GND.
All logic inputs have 1.8V logic compatible thresholds,
allowing for both TTL and CMOS logic compatibility
when operating in the valid supply voltage range. Fail-
Safe Logic circuitry allows voltages on the control pins
to be applied before the supply pin, protecting the
device from potential damage.
The TMUX113x devices are part of the precision
switches and multiplexers family. These devices have
very low on and off leakage currents and low charge
injection, allowing them to be used in high precision
measurement applications. A low supply current of
8nA enables use in portable applications.
