PCA1070
TEST AND APPLICATION INFORMATION
The test circuit is illustrated in Fig.7. The basic application circuit is illustrated in Fig.8. An interrupter with an N-channel
depletion MOS transistor (e.g. BSD254A or BSP124) is shown. It is intended for applications where a low DC line voltage
is required. An interrupter with an N-channel enhancement MOS transistor (e.g. BSN304A or BSP130) can be used for
applications where a relatively high DC line voltage is allowed.
An application circuit for applications where a low DC line voltage and long line interrupts are required, is illustrated in
Fig.9 (interrupter with an N-channel depletion MOS transistor).
