The onsemi HCPL2601V is a single-channel high-speed optocoupler with a 10 Mbps data rate, 2500 Vrms isolation, and an open collector output in an 8-DIP through-hole package (cites:,). The 10 Mbps data rate suits it for isolating digital communication links like CAN, RS-485, or industrial fieldbus interfaces where the signal integrity across the isolation barrier matters more than raw throughput (cites:). The 75 ns propagation delay and 50 ns rise / 12 ns fall times set the timing budget for the data path — a 10 Mbps NRZ signal has a 100 ns bit period, so the 75 ns delay consumes 75% of the bit window, leaving 25 ns margin for the receiver and trace skew (cites:,).
Isolation and transient immunity for industrial noise environments
Rated for 2500 Vrms isolation, the HCPL2601V provides galvanic separation between the logic-side and field-side circuits in motor drives, PLC I/O modules, and power converters (cites:). The 5 kV/µs minimum common-mode transient immunity means the output stays stable when a fast voltage transient (like a motor drive switching edge) couples across the isolation barrier — without this rating, the output could glitch and corrupt the data stream (cites:).
onsemi lists the HCPL2601V as Obsolete, meaning the manufacturer has discontinued production with no last-time-buy window remaining (cites:). New-old-stock and surplus inventory are available through independent distribution channels; quantities are lot-specific and confirmed at RFQ time (cites:).
