DESCRIPTION
The LH1505 contains two normally open switches that can
be used as two independent SPST relays or as one DPST
relay. The relay is constructed using a GaAlAs LED for
actuation control and integrated monolithic dies for the
switch outputs. The die, fabricated in a high-voltage
dielectrically isolated technology, is comprised of a
photodiode array, switch control circuity, and DMOS
switches. In addition, the LH1505 relay employs current
limiting circuitry, enabling it to pass lightning surge testing
as per ANSI/TIA-968-B and other regulatory voltage surge
requirements when overvoltage protection is provided.
APPLICATIONS
• General telecom switching
- 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.
