PCA9536DGKR TI I/O Expanders

The PCA9536 is a 4-bit remote I2C I/O expander with interrupt output, operating from a 2.3-V to 5.5-V supply. It supports I2C bus speeds up to 400-kHz, provides 4 GPIO pins that can be independently configured as inputs or outputs with built-in pull-up resistors, and includes an open-drain interrupt output for input change notification. Three address pins allow up to eight devices on the same bus (32 total I/Os). Packaged in an 8-pin VSSOP (DGK), it is ideal for expanding GPIO capabilities of microcontrollers in portable electronics, server management, and industrial controls requiring minimal I/O expansion.
