The Everlight 6N137 is a high speed optocoupler with a 10Mb DC input. It is designed to provide electrical isolation while transmitting data speeds up to 10Mb per second in harsh environments, such as industrial and automotive applications. It features high common-mode transient immunity, low propagation delay, and Schmitt trigger inputs for increased noise immunity. It can be used in applications ranging from microcontrollers and PLCs to anti-lock brake systems and inverters.
