PCA6107 Operating Power-Supply Voltage Range The PCA6107 consists of one 8-bit Configuration 5.5V (inputor output selection), Input Port, Output Port,
and Polarity Inversion (active high) registers. At• 5-V Tolerant I/O Ports power on, the I/Os are configured as inputs.• 400-kHz FastI2C Bus However, the system master can enable the I/Os as• Three Hardware Address Pins Allow for Use either inputs or outputs by writing to the I/O Eight Deviceson theI2 C/SMBus configuration bits. The data for each inputor outputis
