Overview
The HCPL2631SDM is a dual-channel high-speed logic gate optocoupler produced by onsemi. This component is part of the HCPL2631 series, which 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 data transmission and offers superior common mode rejection (CMR) and a wide operating temperature range.
Although the HCPL2631SD is obsolete, the HCPL2631SDM is a recommended substitute, ensuring continued support for high-performance applications.
