PCA6408A
Low-voltage, 8-bit I2C-bus and SMBus I/O expander
7.5 I/O port
When an I/O is configured as an input, FETs Q1 and Q2 are off, which creates a
high-impedance input. The input voltage may be raised above VDD to a maximum of 5.5 V.
If the I/O is configured as an output, Q1 or Q2 is enabled, depending on the state of the
Output port register. In this case, there are low-impedance paths between the I/O pin and
either VDD(P) or VSS. The external voltage applied to this I/O pin should not exceed the
recommended levels for proper operation.
On power-up or reset, all registers return to default values.
