'COMMENT

Stresses above those listed under"Absolute Maximum

Ratings" may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at these·or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may

affect device reliability.

NOTES: 1. VBB must be applied prior to Vcc and Voo. VBB must also be the last power supply switched ofl.

2.Typical values are for TA = 25'Cand nominal supply voltages.

3.The total power dissipation Is not calculated by summing the various currents (1 00• Icc, and IBB) multiplied by their respective vol· tages since current paths exist between the various power supplies and Vss. The 100. Icc. and IBB currents should be used to deter· mine power supply capacity only.

4.IBB for the 2708L Is specified in the programmed state and is lSmA maximum In the unprogrammed state.
