7.5 Thermal Shutdown
The TMUX9832ZEH offers a thermal shutdown safety feature to make sure the device does not continue
to operate once internal temperatures exceed the thermal shutdown temperature defined in the data sheet.
When the TMUX9832ZEH enters thermal shutdown, the /THERM pin asserts low and all switches is disabled.
The TMUX9832BGAEVM implements an easy to identify thermal shutdown indicator circuit in which an LED
illuminates if the device enters this condition (only if the J13 header is placed on the EVM). Once the device exits
the thermal shutdown state, the LED turns off, the switches assumes the appropriate state based on the current
digital input conditions, and the /THERM pin goes into a high impedance state.
