HCPL2601VM

Logic Output Optoisolators Overview

The HCPL2601VM is a single-channel high-speed logic gate output optocoupler manufactured by onsemi. It features an 850 nm AlGaAs LED coupled to a high-speed integrated photodetector logic gate with an open-collector output and Schottky clamp. The device supports data rates up to 10 Mbps with typical propagation delays of 75 ns (tpLH/tpHL). It provides a minimum common-mode transient immunity (CMTI) of 5 kV/µs and an isolation voltage of 2500 Vrms. Operating parameters include a maximum DC forward current of 30 mA, a typical forward voltage of 1.4 V, and a maximum output current of 50 mA per channel. The component operates within a temperature range of -40°C to 100°C and is housed in an 8-PDIP package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix VM corresponds to the 8-PDIP tube packaging format when sourcing. Confirm that the 2500 Vrms isolation rating meets the safety requirements of the target application environment. Check for RoHS compliance status as manufacturing sources may vary. Ensure the open-collector output interface aligns with the receiving circuit's pull-up resistor configuration. Validate the operating temperature range against the intended thermal conditions.

Logic Output Optoisolators Selection Notes

Select this component for applications requiring high-speed digital isolation with TTL-compatible input thresholds. The open-collector output allows for flexible wired-OR configurations and voltage level shifting. Consider the 10 Mbps data rate limit when designing for higher bandwidth signals. The Schottky clamp feature makes it suitable for pulse transformer replacement scenarios where fast turn-off times are critical. Evaluate the 8-PDIP package constraints for PCB layout space.

Logic Output Optoisolators Part Context

This device belongs to the HCPL-26xx series of high-speed logic gate optocouplers from onsemi. It serves as a successor or equivalent to older HCPL-2601 variants, offering improved speed and reliability. The series is designed for applications demanding reliable digital isolation between different ground potentials. It shares functional similarities with other members like the HCPL-2611 but differs in channel count and specific CMR ratings.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include HCPL2601M. Designers should verify pinout compatibility and electrical parameter equivalence before substitution. The HCPL26xxM series is recommended as the new equivalent part number for new designs.
