PCA95380, PCA9538, Remote 8-Bit I2C AND SMBus Low-power I/O Expander
This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation.
It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data (SDA)].
The PCA9538 consists of one 8-bit Configura
