## **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. 

- 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 

- (1) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through hole devices (DIP) 

- (2) Breakdown occurs between the output pins external to the package 

- (3) Refer to current limit performance application note for a discussion on relay operation during transient currents
