DESCRIPTION
The PS7241C-1A is a solid state relay containing GaAs LEDs
on the light emitting side (input side) and MOS FETs including
current control circuit on the output side. The currrent control
circuit of the OCMOS FET protects this device from thermal
breakdown and output circuit.
It is suitable for analog signal control because of its low offset
and high linearity.
