Data Sheet
November 1999
L7581 Ringing Access Switch
Electrical Characteristics
(continued)
Table 6. Ring Return Switch, 3
* 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 7. Ringing Access Switch, 4
* 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 Lucent Technologies Microelectronics Group 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.
