DESCRIPTION

The PS7241E-1A is an optically coupled element that combines a GaAs infrared LED on the input side with a

normally-open MOS FET on the output side to realize an excellent cost performance.

The small, thin package and high sensitivity of this element makes it ideal for battery-driven mobile devices, and its

small offset voltage at power-on and good linearity are also make it suitable for controlling micro analog signals.
