* 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.
