MikroElektronika 8 Bit I/O Expander From Texas Instruments TCAL6408 8 bit Expansion Module for And LEDs, Applications

The MikroElektronika Expander With Interrupt Output provides general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol. The device can operate with a power supply voltage ranging from 1.08 V to 3.6 V on the I2C bus side (VCCI) and a power supply voltage ranging from 1.08 V to 3.6 V on the P-port side (VCCP).
