10 Mbps digital isolation for PLC and motor-drive interfaces
The HCPL0600 is a single-channel optoisolator from onsemi with a 10 Mbps data rate, open collector output, and 3750 Vrms isolation — a standard fit for isolating digital logic signals in PLC I/O, motor-drive feedback, and industrial communication links. The 50 ns typical rise time and 12 ns fall time, combined with a 75 ns max propagation delay, keep the signal edge distortion low enough for 10 Mbps NRZ data without bit errors.
Operates from a 4.5 V to 5.5 V supply, making it directly compatible with 5 V logic families (TTL, CMOS). The open collector output can be pulled up to the same rail or a different voltage within the 50 mA per-channel output current limit. The input is DC-coupled with a forward voltage of 1.75 V max and a maximum forward current of 50 mA — standard drive levels from a microcontroller GPIO or logic gate output.
Common-mode transient immunity for noisy environments
Minimum common-mode transient immunity of 5 kV/µs means the output does not glitch when a fast voltage transient (e.g., from an IGBT switching at 10-20 kV/µs) couples across the isolation barrier — a key spec for motor-drive and inverter applications.
The 8-SOIC (0.154", 3.90 mm width) footprint is industry-standard and shared with many 6N137-class optocouplers. For tape-and-reel quantities, the companion order code is HCPL0600R2 — confirm the packaging suffix before ordering if your pick-and-place line requires reel feed.
