Working Principle

The EL1507CSZ isolator isolates input signals from the output side by utilizing a three-port design. The input side of the EL1507CSZ contains the signal ports, which are grouped in either pairs or single input pairs. The output side of the EL1507CSZ contains output ports, each of which is connected to a single input port. An electrical isolation barrier exists between the input side and the output side, ensuring that the output side does not receive any energy from the input side.

The EL1507CSZ isolator offers a degree of isolation rating of 1 KV RMS, and typically operates on a supply voltage of 3.3V, 5V and 12V. This Isolator features protection against extreme temperature variation and electrical over-stress. It also features common-mode filtration by means of USB filters, capacitors and resistors. This Isolator also features a reverse current protection, and is available in various packages including DIP, SIL and QFN.
