TCA6408ARSVR

Description
The TCA6408ARSVR is an 8-bit I²C and SMBus I/O Expander provides 8-bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I²C bus (or SMBus) protocol. This device can operate with a power supply voltage ranging from 1.65 to 5.5V on both the I²C bus side (VCCI) and on the P-port side (VCCP). This allows the TCA6408A to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of microprocessors and microcontrollers, some PCB components such as LEDs remain at a 5V power supply.
The device supports both 100kHz (standard-mode) and 400kHz (fast-mode) clock frequencies. It provides a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans and so forth.
