Functional Description
The 74F821 consists of ten D-type edge-triggered flip-
flops. This device has 3-STATE true outputs for bus sys-
tems organized in a broadside pinning. The buffered Clock
(CP) and buffered Output Enable (OE) are common to all
flip-flops. The flip-flops will store the state of their individual
D inputs that meet the setup and hold times requirements
on the LOW-to-HIGH CP transition. With the OE LOW the
content of the 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.
