The CPC5001 is a non-inverting digital optical isolator with buffered-logic inputs and open-drain outputs. Channel 1 propagates a signal from SideA to SideB, while Channel 2 sends a signal from SideB to SideA. It provides galvanic isolation across voltage differences up to 3750Vrms . 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. It functionally replaces two logic buffers and two single-channel optoisolators. Internal bandgap references regulate the LED drive currents to 3mA to reduce peak power requirements.

Unlike transformer or capacitive isolators, optical isolation passes DC signals, and does not need to be clocked periodically to refresh state. Buffered signals will always return to their proper value after a transient interruption at either side.

Features:

  • Isolates One Signal in Each Direction
