- Ring delay

DESCRIPTION

The LH1521 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.

- 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.

Breakdown occurs between the output pins external to the package.

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

hole devices (DIP).
