*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 VCC is greater than 2.7V.
