Overview
The HCPL2631M is a dual-channel high-speed logic gate optocoupler produced by onsemi. It consists of an 850 nm AlGaAs LED optically coupled to a very high-speed integrated photo-detector logic gate. This device features a strobable output with an open collector, allowing for wired OR outputs. The switching parameters are guaranteed over a temperature range of -40°C to +85°C, ensuring reliable operation in various environments.
The HCPL2631M is designed to provide superior common-mode rejection, typically 10 kV/µs, and a minimum common-mode transient immunity (CMR) of 5 kV/µs. This makes it suitable for applications requiring high-speed data transmission and isolation.
