Notes:
(1) The SMH4042A will drive the Reset outputs and voltage control signals 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.
(2) A, B,G, H, K. L, M, & N refer to the Part Number Suffix.
(3) For TA = –10ºC to 85ºC.
