TPT29555 Description
The TPT29555 is a 16-bit GPIO expander with interrupt and weak pull-up resistors for I2C-bus applications. The power supplier voltage range is from 1.65 V to 5.5 V that allows the TPT29555 to interconnect with 1.8-V microcontrollers. The TPT29555 contains the register set of two pairs of 8-bit Configuration, Input, Output, and Polarity Inversion registers.
