ACPL-W60L/K63L optically coupled gates are optically coupled gates that combine a GaAsP light emitting diode and an integrated high gain photo detector. They provide maximum AC and DC circuit isolation while achieving LVTTL/LVCMOS compatibility.
The ACPL‑W60L and ACPL‑K63L are high‑speed optically coupled gates that combine a GaAsP LED with a high‑gain photodetector. Their output is an open‑collector Schottky‑clamped transistor, offering LVTTL/LVCMOS compatibility and a common‑mode transient immunity of 15 kV/µs. They are designed for isolated line‑receiver, computer‑peripheral, and microprocessor interface applications, and can be used for digital isolation in A/D and D/A conversion or switching power supplies.
Key specifications include a typical data rate of 15 MBd, low input current (5 mA), operating temperature range –40 °C to +85 °C, and safety approvals from UL, CSA, and IEC/EN/DIN standards. The devices are offered in stretched SO‑6 (ACPL‑W60L) and stretched SO‑8 (ACPL‑K63L) packages, with detailed mechanical drawings, electrical ratings, and recommended solder‑reflow profiles provided in the sheet.
