8.4 Device Functional Modes

When the EN pin of the TMUX6219-Q1 is pulled high, one of the switches is closed based on the state of the

SEL pin. When the EN pin is pulled low, both of the switches are in an open state regardless of the state of the

SEL pin. The control pins can be as high as 36 V.

The TMUX6219-Q1 can be operated without any external components except for the supply decoupling

capacitors. The EN pin has an internal pull-up resistor of 4 MΩ and SEL pin has internal pull-down resistor of 4

not consume additional current as highlighted in Implications of Slow or Floating CMOS Inputs. Unused signal

path inputs (S1, S2, or D) should be connected to GND.
