HCPL-2202

Logic Output Optoisolators Overview

The HCPL-2202 is a high-speed optocoupler featuring a single channel with a 5 MBd data rate. It utilizes a GaAsP LED and includes an optical receiver with built-in Schmitt triggers for logic-compatible waveforms. The device offers a 3750 Vrms isolation voltage and a common-mode transient immunity of 1 kV/µs. It employs a push-pull totem pole output stage capable of sourcing or sinking 25 mA. Key electrical parameters include a maximum forward current of 5 mA, a typical forward voltage of 1.5 V, and a power dissipation of 210 mW. Propagation delays are typically 30 ns for rise and 7 ns for fall times.

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix (e.g., -000E) to confirm the exact package type and tape/reel configuration, as suffixes define physical attributes rather than function. Ensure compliance with RoHS directives by checking the specific variant's certification status. Confirm the operating temperature range requirements against the datasheet specifications before finalizing procurement decisions.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel high-speed isolation solution with logic-compatible outputs is required. The integrated Schmitt triggers make it suitable for applications demanding noise immunity without external buffering. Consider the 5 MBd speed limit and 3750 Vrms isolation rating against system requirements. The totem pole output simplifies interface design compared to open-collector alternatives.

Logic Output Optoisolators Part Context

This part belongs to the Broadcom HCPL-22XX series of optically coupled logic gates. The series shares architectural similarities with the HCPL-2201 and HCPL-2211, differing primarily in channel count and specific electrical characteristics. These devices are designed for applications requiring robust signal isolation with fast switching speeds.

Logic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include HCPL-2201 and HCPL-2211, depending on channel count requirements. Verify pinout compatibility and electrical parameter alignment, specifically propagation delay and output current capabilities, before implementing any cross-model replacement.

Logic Output Optoisolators FAQ

What is the purpose of the built-in Schmitt triggers?

The built-in Schmitt triggers condition the input signal to provide clean, logic-compatible output waveforms, enhancing noise immunity and signal integrity.

How does the totem pole output benefit the circuit design?

The totem pole output allows the device to actively source and sink current, eliminating the need for external pull-up resistors often required with open-collector outputs.
