FUNCTIONAL DESCRIPTION
The F534 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 times requirements 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.
