DESCRIPTION/ORDERING INFORMATION

This 16-bit I/O expander for the two-line bidirectional bus (I²C) is designed for 1.65-V to 5.5-V V_CCoperation. It

provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface [serial clock

(SCL), serial data (SDA)].

The TCA9535 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity

Inversion (active-high or active-low operation) registers. At power on, the I/Os are configured as inputs. The

system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for

each input or output is kept in the corresponding Input or Output Port register. The polarity of the Input Port

The system master can reset the TCA9535 in the event of a timeout or other improper operation by utilizing the

power-on reset feature, which puts the registers in their default state and initializes the I²C/SMBus state machine.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
