8 PIN DIP TYPE PS7122-2B
OPTO-COUPLED SOLID STATE RELAY PS7122L-2B
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.
APPLICATIONS
• VOICE TELEPHONY
• X-CHANGER
• PBX
