PCA95380 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.
