ZHCSMO5F November 2020 – July 2024 TMUX7219
PRODUCTION DATA
When the EN pin of the TMUX7219 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 44 V.
The TMUX7219 can operate 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 MΩ. If unused, EN pin must be tied to VDD and SEL pin must be tied to GND to ensure the device does 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.
