Functional Description
The LCX821 consists of ten edge-triggered flip-flops with
individual D-type inputs with 3-STATE true outputs. The
buffered clock and buffered Output Enable are common to
all flip-flops. The ten 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 (CLK) transition.
With the Output Enable (OE) LOW, the contents of the ten
flip-flops are available at the outputs. When 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.
