The TPT29555A is a 16-bit GPIO expander withinterruption and weak pull-up resistors for I2C-busapplications. The power supplier voltage range is from 1.65V to 5.5 V, allowing the TPT29555A to interconnect with1.8-V microcontrollers.The TPT29555A contains the register set of two pairs of 8-bit Configuration, Input, Output, and Polarity Inversionregisters. The open-drain interrupt ( INT ) output ischangeable when any input state changes from its relatedregister state and is used to indicate the system master thatan input state has changed.INT can be connected to theinterrupt input of a microcontroller. By sending an interruptsignal on this line, the remote I/O can inform themicrocontroller if there is incoming data on its ports withouthaving to communicate via the I2C-bus. Thus, theTPT29555A can remain a simple slave device. The poweron reset sets the registers to their default values andinitializes the device state machine.All input/output pins have internal weak pull-up resistors toremove external components. Three hardware pins (A0, A1,A2) select the fixed I2C-bus address and allow up to eightdevices to share the same I2C-bus.TPT29555A is available in TSSOP24 and QFN24packages and is characterized from −40°C to +85°C.
