Functional Description
The ’F175 consists of four edge-triggered D flip-flops with
individual D inputs and Q and Q outputs. 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 out-
puts LOW and Q outputs HIGH independent of Clock or
Data inputs. The ’F175 is useful for general logic applica-
tions where a common Master Reset and Clock are accept-
able.
