Functional Description
The VHC175 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 outputs LOW and Q outputs HIGH inde-
pendent of Clock or Data inputs. The VHC175 is useful
for general logic applications where a common Master
Reset and Clock are acceptable.
