FEATURES
CONTAINS NORMALLY CLOSE OUTPUT (MOSFET)
DESIGNED FOR AC/DC SWITCHING LINE CHANGER
DUAL CHANNEL 8 PIN DIP PACKAGE
DESCRIPTION
PS7122-2B and PS7122L-2B are solid state relays containing
a GaAs LED on the light emitting side (input side) and MOSFETs
on the output side. They are suitable for analog signal control
because of their low offset and high linearity.
