Digital isolators are a type of electronic device used to electrically isolate two circuits from each other. They provide excellent galvanic isolation to allow signals to pass from one circuit to another while preventing the electron flow and providing noise immunity. The HCPL-0900-000E is a digital isolator composed of two independent sections, which allows one-way signal transmission between two circuits.The HCPL-0900-000E can be used in an array of applications, including data transfer between isolated systems, fault protection in industrial automation equipment, isolating circuits from high voltage signals, and separating digital circuits from analog instrumentation. It offers a transmission rate of up to 5 Mbps and low propagation delay of 1.30 µs typical. It provides superior operation in the presence of noise signals, with low propagation delay variation (PDV) over the specified temperature range (0 to 70°C).When used in systems with power supplies, the HCPL-0900-000E is important in preventing the floating ground potential from becoming a ground reference. This reduces power supply compatibility and noise problems in the system.The working principle of the HCPL-0900-000E is based on optically coupling two sections together: an input circuit and an output circuit. This optical or electrical isolation allows for a high voltage signal or data signal to be transferred between two relatively isolated circuits while still keeping the two circuits electrically isolated from each other.The HCPL-0900-000E utilizes a high gain, forward-biased photodiode, which is activated when the output of the input circuit is high. This photodiode activates a matched emitter-coupled logic (ECL) output circuit. This ECL output circuit is out of phase from the input circuit, thereby providing the shift between the input and output signals.The HCPL-0900-000E utilizes a thin-film technology to provide temperature-compensated propagation delay through its use of a high gain LED, which is incorporated with symmetrical common mode transient immunity performance. This architecture also provides the ability to maintain low propagation delays over the entire specified temperature range. Another feature of the HCPL-0900-000E is a low input to output common mode transient immunity (CMTI) performance of -30 dB at frequencies up to 500 kHz.The HCPL-0900-000E can be configured to accept a variety of input levels, such as TTL, LVCMOS and ECL. It also offers two-way signaling and remote control of the output, allowing the user to control the signal and respond to an input signal.In conclusion, the HCPL-0900-000E is one of the best digital isolators for applications that require fast signal transmission, low propagation delay variation, and low common mode transient immunity performance. It is designed to provide a reliable, efficient, and economical solution for isolating two circuits while assuring noise immunity and excellent noise performance.
