Advance Information
TABLE 4: Absolute Maximum Ratings*
*
Stresses greater than those listed above 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 operating section of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
TABLE 5: Operating Characteristics (Over specified Temperature Range)
1. This device assumes a standby mode if the chip is disabled (CE1 high or CE2 low). It will also go into a standby mode whenever
if both UB and LB are high. In order to achieve low standby current all inputs must be within 0.2 volts of either VCC or VSS.
2. The Chip is Disabled when CE1 is high or CE2 is low. The Chip is Enabled when CE1 is low and CE2 is high.
