Overview
The HCPL2631SD is a dual-channel high-speed logic gate optocoupler produced by onsemi. This component is part of the HCPL2631 series, which is designed for high-speed data transmission and isolation. Although the HCPL2631 series is not recommended for new designs (with the HCPL26xxM series being the recommended replacement), it remains a significant component in existing systems. The optocoupler features an 850 nm AlGaAS LED optically coupled to a high-speed integrated photo-detector logic gate, ensuring reliable and fast data transfer.
The device operates over a wide temperature range of -40°C to +85°C and is known for its superior common mode rejection (CMR) and high data rate of 10 MBit/s. It is particularly useful in applications requiring high-speed data transmission and electrical isolation.
