APPLICATIONS
• General telecom switching
DESCRIPTION
The LH1523 dual 1 form B relays are SPST normally closed
switches that can replace electromechanical relays in many
applications. The relays are constructed as a multi chip
hybrid device. Actuation control is via an infrared LED. The
output switch is a combination of a photodiode array with
MOSFET switches and control circuity.
- On/off hook control
- Ring delay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
