HCPL-0201#500

Logic Output Optoisolators Overview

The HCPL-0201#500 is a high-speed logic output optocoupler from Broadcom Limited, housed in an 8-SOIC surface-mount package. It features a single channel with a data rate of 5 Mb/s and an isolation voltage of 3750 Vrms. The device utilizes a GaAsP LED input and a detector with a totem pole output and built-in Schmitt trigger. Key electrical parameters include a typical forward voltage of 1.5 V, maximum forward current of 10 mA, and supply voltage range of 4.5 V to 20 V. Output characteristics specify a sink current of 25 mA and propagation delay of 300 ns. Operating temperature spans -40°C to +85°C.

Logic Output Optoisolators Feature Summary

• Integrates a GaAsP light-emitting diode with a photodetector featuring a totem pole output stage for direct logic compatibility.
• Incorporates a built-in Schmitt trigger at the receiver input to provide hysteresis, eliminating the need for external waveform shaping circuits.
• Delivers high common-mode transient immunity of 1 kV/µs to ensure signal integrity in noisy environments.
• Supports wide supply voltage operation ranging from 4.5 V to 20 V, compatible with TTL, LSTTL, and CMOS logic levels.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #500 indicates the tape-and-reel packaging format compared to tube variants. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the ordering part number matches the required package style and reel quantity specifications for your assembly line.

Logic Output Optoisolators Selection Notes

Select this component when digital signal isolation requires high speed up to 5 Mb/s without external signal conditioning. The integrated Schmitt trigger simplifies design by handling slow input edges. Consider the 3750 Vrms isolation rating for safety-critical applications requiring robust galvanic separation between input and output domains.

Logic Output Optoisolators Part Context

This device belongs to the HCPL-02XX series of logic gate optocouplers manufactured by Broadcom Limited (formerly Avago). It shares architectural similarities with the HCPL-22XX series but differs in LED material composition. The series is designed for applications demanding fast response times and reliable logic-level transmission across isolation barriers.

Logic Output Optoisolators Replacement Considerations

HCPL-0201-000E: Identical functional specifications; verify if the -000E suffix denotes tube packaging instead of tape-and-reel.

Logic Output Optoisolators FAQ

Does the HCPL-0201#500 require external pull-up resistors?

No, the device features a totem pole output that actively drives both high and low states, eliminating the need for external pull-up resistors.

What is the purpose of the internal Schmitt trigger?

The internal Schmitt trigger provides hysteresis to clean up noisy or slowly changing input signals, allowing the device to produce sharp, logic-compatible output waveforms without additional circuitry.
