TPT29555 Datasheet PDF (I2C to 16-bit GPIO Expander)

TPT29555 - I2C to 16-bit GPIO Expander

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.

Features

I2C-bus to 16-bit GPIO expander.
