Functional Description
The VHC374 consists of eight edge-triggered flip-flops
with individual D-type inputs and 3-STATE true outputs.
The buffered clock and buffered Output Enable are
common to all flip-flops. The eight flip-flops will store the
state of their individual D inputs that meet the setup and
hold time requirements on the LOW-to-HIGH Clock (CP)
transition. With the Output Enable (OE) LOW, the con-
tents of the eight flip-flops are available at the outputs.
When the OE is HIGH, the outputs go to the high imped-
ance state. Operation of the OE input does not affect the
state of the flip-flops.
