BV EI 541 1129 is a Hahn Electronics integrated circuit (IC). It is an integrated opto-coupler, which is an electrical component that is used to transfer electric signals from a circuit to another, isolated circuit using an optical light signal. It can be used in a variety of applications, such as data transmission, signal isolation, and analog signal switching. This particular opto-coupler has two 4-pin connectors, a control signal input, signal input/output, and a ground connection. It is able to operate over a wide range of temperatures, between -40 and +85C. Additionally, it features a low signal to noise ratio, high speed switching with a response speed of 600Hz, and a high reliability.
