Overview
The TPT29536A is a 4-bit GPIO expander with interruption and weak pull-up resistors for I2C-bus applications. The power supplier voltage range is from 1.65 V to 5.5 V, allowing the TPT29536A to interconnect with 1.8-V microcontrollers.
The TPT29536A contains the register of 4-bit Configuration, Input, Output, and Polarity Inversion registers. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The power-on reset sets the registers to their default values and initializes the device state machine.
All input/output pins have internal weak pull-up resistors to remove external components.
TPT29536A is available in the MSOP8 package.
