LOW VOLTAGE 16-BIT I 2 C AND SMBus LOW-POWER I/O EXPANDER WITH INTERRUPT OUTPUT, RESET, AND CONFIGURATION REGISTERS

This 16-bit I/O expander for the two-line bidirectional bus (I C) is designed for 1.65-V to 5.5-V VCC operation. It 2 provides general-purpose remote I/O expansion for most Microcontroller families via the I C Interface [serial Clock (SCL), serial data (SDA)]. The TCA9539 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 Register The polarity of the Input Port Register CAN be inverted with the Polarity Inversion Register All Registers CAN be read by the system master.
