DESCRIPTION
The LH1502 relays contain normally open and normally
closed switches that can be used independently as a 1 form
A and 1 form B relay, or when used together, as a 1 form C
relay. 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.
APPLICATIONS
• General telecom switching
- On/off hook control
- Ring delay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls

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.
