8 PIN DIP TYPE PS7122-2B
OPTO-COUPLED SOLID STATE RELAY PS7122L-2B
FEATURES
鈥?CONTAINS NORMALLY CLOSE OUTPUT (MOSFET)
鈥?DESIGNED FOR AC/DC SWITCHING LINE CHANGER
鈥?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.
