TCA6424A - Low-Voltage 24-Bit I2C and SMBus I/O Expander
This 24-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) and serial data (SDA)].
The major benefit of this device is its wide VCC range.
It can operate fro
