TCA6418E Description
/ORDERING INFORMATION The TCA6418E is a 18 channel GPIO expansion device with integrated ESD protection. It can operate from 1.65 V to 3.6 V and has 18 general purpose inputs/outputs (GPIO) that can be used via the I2C interface [serial clock (SCL), serial data (SDA)]. The major benefit of this device is it frees up the processor from having to individually monitor changes in multiple inputs and also frees up the...
