Overview
The HCPL2601SD is a high-speed logic gate optocoupler produced by onsemi. This single-channel optocoupler features an 850 nm AlGaAS LED optically coupled to a very high-speed integrated photo-detector logic gate. The device is designed for high-speed applications, offering a data rate of up to 10 Mbit/s. Although the HCPL2601 series is not recommended for new designs (with the HCPL26xxM series being the recommended replacement), it remains a significant component in existing systems due to its robust specifications and features.
