DESCRIPTION
The LH1546AEF (4 pin SOP) is robust, ideal for telecom and
ground fault applications. It is an SPST normally open
switch (1 form A) that replaces electromechanical relays in
many applications. It is constructed using a GaAs LED for
actuation control and MOSFETs for the switch output. In
addition, it employs current-limiting circuitry which meets
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 relay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls
Note
• See “solid-state relays” (application note 56)
AGENCY APPROVALS
• UL1577, file no. E52744 system code O
• BSI/BABT certification no. 8500 issue 2

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.
