Data Sheet
February 2001
L7583A/B/C/D Line Card Access Switch
Electrical Characteristics (continued)
Table 9. Ring Return Switch, 7
* This parameter is not tested in production. Choice of secondary protector should ensure this rating is not exceeded.
Applied voltage is 100 Vp-p square wave at 100 Hz.
Table 10. Ringing Access Switch, 8
* At the time of publication of this data sheet, the current device design will be a nominal 4 mA. Devices are being redesigned to reduce this current to less
than 2 mA nominally. Consult your Legerity account executive for additional details.
Choice of secondary protector and series current-limit resistor should ensure these ratings are not exceeded.
Applied voltage is 100 Vp-p square wave at 100 Hz.
