DESCRIPTION
- Load voltage 400 V
The LH1539 telecom switch consists of an optically isolated
solid-state relay (SSR) form A and a bidirectional input
optocoupler in a single 8-pin package. The SSR is ideal for
switch hook and dial-pulse switching while the optocoupler
performs ring detect and loop current sensing functions.
Both the SSR and optocoupler provide 5300 VRMS of
input-to-output isolation voltage.
- Load current 120 mA
- Current limit protection
- Linear, AC/DC operation
- Clean bounce free switching
- Low power consumption
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
The SSR is integrated on a monolithic receptor die using
smart power technology. The SSR features low On
resistance, high breakdown voltage, and current-limit
circuitry that protects the relay from telephone line induced
lightning surges.
APPLICATIONS
• General telecom switching
- On/off hook switching
The optocoupler provides bidirectional current sensing via
two anti parallel GaAs infrared emitting diodes. Very high
current transfer ratio (CTR) is achieved by coupling to a
photodarlington transistor. This high CTR allows the user to
minimize the size of the ring detector capacitor.
- Dial pulse
- Ring current detection
- Loop current sensing

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.
