L7583A/B/C/D Line Card Access Switch
Electrical Characteristics (continued)

* Temperature shutdown flag (TSD) will be high during normal operation and low during temperature shutdown state.
Zero Cross Current Turn Off
The ring access switch (SW8) is designed to turn off on the next zero current crossing after application of the appropriate logic
input control. This switch requires a current zero cross to turn off. Switch 8, once on, will remain in the ON state (regardless of
logic input) until a current zero cross. Therefore, to ensure proper operation of switch 8, this switch should be connected, via
proper impedance, to the ringing generator or some other ac source. Do not attempt to switch pure dc with switch 8. The ring-
ing test access switch, SW6, also has similar characteristics to switch 8 and should also only be used to switch signals with
zero current crossings. For a detailed explanation of the operation of switches 6 and 8, please refer to the An Introduction to
L758X Series of Line Card Access Switches Application Note.
