The Clock and Master Reset are common. The four flip- flops will store the state of their individual D inputs on the LOW-to-HIGH clock (CP) transition, causing individual Q and Q outputs to follow. A LOW input on the Master Reset (MR) will force all Q outputs LOW and Q outputs HIGH independent of Clock or Data inputs. The AC/ ACT175 is useful for general logic applications where a common Master Reset and Clock are acceptable. Truth Table H = HIGH Voltage Level L = LOW Voltage Level tn = Bit Time before Clock Pulse tn+1 = Bit Time after Clock Pulse Logic Diagram Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
