Overview
® 74AC574 OCTAL D-TYPE FLIP FLOP WITH 3 STATE OUTPUT NON INVERTING s s s s s s s outputs will be set to logic state that were setup at the D inputs.
s While the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) s and while high level the outputs will be in a high DESCRIPTION impedance state.
