CPC5001 Dual, One Channel Each Direction Digital Optical Isolator INTEGRATED CIRCUITS DIVISION Features Description Isolates One Signal in Each Direction The CPC5001 is a dual, non-inverting digital optical Operates From 2.7V to 5.5V isolator with buffered-logic inputs and open-drain Buffered Inputs - No External LED Drive Required outputs. Channel 1 propagates a signal from Side A to Voltage Level Translation Side B, while Channel 2 sends a signal from Side B to Hysteresis at Inputs for Noise Rejection Side A. It provides galvanic isolation up to 3750V . rms Slew-Limited Drivers Reduce EMI When the two sides are powered by supplies with Power-Down to Hi-Z Does Not Load Outputs different voltages, it also functions as a logic level 5Mbaud Data Rate translator for supply voltages as low as 2.7V or as high 8-Pin DIP or Surface Mount Packages as 5.5V. Available in 8-pin DIP and surface mount packages, it functionally replaces two logic buffers and Applications two single-channel optoisolators. Internal bandgap Isolated Signal Monitoring and Control references regulate the LED drive currents to 3mA to Power-Over-Ethernet reduce peak power requirements. Power Supply High-Side Interface Logic-Level Translation Unlike transformer or capacitive isolators, optical Microprocessor System Interface isolation passes DC signals, and does not need to be 2 clocked periodically to refresh state. Buffered signals Inter-Integrated Circuit (I C) Interface will always return to their proper value after a transient Serial Peripheral Interface (SPI) interruption at either side.
