Functional Description
The LVQ374 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-STATE true outputs. The buff-
ered clock and buffered Output Enable are common to all
flip-flops. The eight flip-flops will store the state of their indi-
vidual D-type inputs that meet the setup and hold time re-
quirements on the LOW-to-HIGH Clock (CP) transition. With
the Output Enable (OE) LOW, the contents of the eight
flip-flops are available at the outputs. When the OE is HIGH,
the outputs go to the high impedance state. Operation of the
OE input does not affect the state of the flip-flops.
