Description
The CPC5903 is a dual, optically isolated, logic-bus
repeater. It isolates two open-drain logic signals while
providing 3750Vrms of galvanic isolation. When the
two sides are powered by different supply voltages, it
also functions as a logic level translator for levels as
low as 2.7V or as high as 5.5V. Because the CPC5903
provides an isolated bidirectional buffer for the I2C
data signal and a unidirectional buffer for the I2C clock
signal, it is best suited for applications where clock
stretching is not required. This configuration also
requires the I2C bus master to be on the Side A bus.
Unlike transformer or capacitive isolators, optical
isolation passes DC signals and does not require
continuous clocking to ensure the proper state is
maintained. The CPC5903 always returns the buffered
signals to their proper state after transient
interruptions on either side.
