PCA9534 - 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 PCA9534 consists of one 8-bit Configura
