Description
The PCA9517AD is a CMOS integrated circuit that provides level shifting between low voltage (down to 0.9 V) and higher voltage (2.7 V to 5.5 V) I2C-bus or SMBus applications. It enables the system designer to isolate two halves of a bus for both voltage and capacitance. The PCA9517AD supports Standard-mode and Fast-mode I2C-bus devices and multiple masters.
