The PS2805-1 with Optocouplers SMD-4 RoHS is a photoelectric isolator component manufactured by Isocom. It can be used for controlling logic signals, logic switching, and pulse-width modulation. This device features two independent, high-efficiency optocouplers, each with two channels. The devices are constructed using CMOS and optically coupled techniques for high-speed, low-current operation. The isolators have a wide operating temperature range, 300uA LED current (typical), and an input voltage range of 3V to 28V. The optocouplers meet the requirements of the RoHS Directive, and are available in an SMD-4 package.
