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 V_CC is greater than 2.7V.
(2) A, B,G, H, K. L, M, & N refer to the Part Number Suffix.
(3) For T_A = –10ºC to 85ºC.
