*COMMENT

Stresses listed under Absolute Maximum Ratings

may cause permanent damage to the device. These

are stress ratings only, and functional operation of

the device at these or any other conditions outside

those listed in the operational sections of this speci-

fication is not implied. Exposure to any absolute

maximum rating for extended periods may affect

device performance and reliability.

Notes:

1. The SMH4042 will drive the reset outputs and voltage control signals to valid levels throughout the operating range of 1V to 5.5V.

The balance of the logic will not be guaranteed operational unless V

CC

is greater than 2.7V.

2. Refer to the ordering information table for all valid combinations of options.
