Functional Description
Truth Table
The LVQ174 consists of six edge-triggered D-type flip-flops
with individual D inputs and Q outputs. The Clock (CP) and
Inputs
Master Reset (MR) are common to all flip-flops. Each D
MR
CP
D
input’s state is transferred to the corresponding flip-flop’s
L
output following the LOW-to-HIGH Clock (CP) transition. A
LOW input to the Master Reset (MR) will force all outputs
H
LOW independent of Clock or Data inputs. The LVQ174 is

all storage elements.
