HCPL2611S

Logic Output Optoisolators Overview

The HCPL2611S is a high-speed logic gate optocoupler featuring an open collector output. It supports data rates up to 10 MBit/s with typical propagation delays of 75 ns and rise/fall times of 50 ns/12 ns. The device provides 2500 Vrms isolation voltage and a minimum common-mode transient immunity (CMTI) of 10 kV/µs. It operates within a temperature range of -40°C to +85°C, accepts DC input, and requires a supply voltage between 4.5 V and 5.5 V.
