Other Parts Discussed in Thread: TCA9539
Dear team,
In BCM design, the input signal will connected to the IO EXPANDER directly, the input signal is 0~24V.
As the IO EXPANDER’s power rail is 3.3V / 5V, normally the GPIO of IO EXPANDER has a clamp diode to make the circuit safe.
Does our device TCA9539 support such function, input signal is 0-24V?
Thanks & Best Regards,
Sherry
