HCPL-4100#300

Overview

The HCPL-4100#300 is a single-channel logic output optocoupler from Broadcom's HCPL series, housed in an 8-pin DIP package. It features a DC input type with a maximum forward voltage of 20V and a typical rise time of 16ns. The device provides an isolation voltage of 3750V AC and operates within a temperature range of -40°C to 85°C. Certified under CSA and UL 1577 standards, it supports a maximum baud rate of 20 KBps and includes internal shielding for high common-mode rejection.

Feature Summary

• Internal shielding design ensures high common-mode rejection capabilities
• Data input compatibility with LSTTL, TTL, and CMOS logic families
• Guaranteed 20 mA loop parameters for reliable current transmission

Applications

• Point-to-point communication systems
• Multi-drop application networks
• Active non-isolated transceiver interfaces

Procurement Notes

Verify the specific suffix #300 against official datasheets to confirm packaging and material compliance. Ensure the component matches the required 8-pin DIP form factor and isolation voltage ratings for your circuit design. Cross-reference certification marks such as UL 1577 and CSA with your regional regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component when interfacing with LSTTL, TTL, or CMOS inputs requiring galvanic isolation. The 20 mA current loop specification suits applications needing robust signal transmission over isolated barriers. Consider the 8-pin DIP package for through-hole mounting constraints and verify that the 20 KBps data rate meets system timing requirements.

Part Context

This part belongs to the HCPL series of optocouplers, designed for digital signal isolation. It functions as a transmitter in current loop configurations, often paired with receiver units like the HCPL-4200. The series emphasizes reliability in industrial environments through certified isolation and wide operating temperature ranges.

Replacement Considerations

Compatible substitutes include the HCPL-4100-000E and HCPL-4100-500E variants within the same family. These alternatives share identical functional specifications but may differ in packaging suffixes or environmental certifications. Verify pinout and electrical parameters match before substitution.
