HCPL-261N-500E

Logic Output Optoisolators Overview

The HCPL-261N-500E is a high-speed optocoupler from the Broadcom HCPL-261N series, featuring a single channel with an open collector output. It supports data rates up to 10 Mb/s and provides electrical isolation of 3750 Vrms. The device operates within a temperature range of -40°C to +85°C and utilizes a PDIP-8 Gull Wing package for surface mount installation. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.5 V, reverse voltage of 3 V, and output current capability of 50 mA. Power dissipation is rated at 60 mW, with rise and fall times of 42 ns and 12 ns respectively.

Logic Output Optoisolators Procurement Notes

Verify RoHS compliance status as documentation indicates potential variations. Confirm availability through authorized distributors due to limited supply conditions noted in some channels. Ensure ordering suffix matches required packaging format. Cross-reference datasheet revisions for updated thermal and electrical specifications before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required with open-collector output compatibility. Consider the 10 Mb/s data rate limit and 3750 Vrms isolation barrier for system design. Evaluate the 8-DIP Gull Wing package constraints for PCB layout. Compare against alternative logic-output optocouplers if push-pull outputs are preferred over open-collector configurations.
