Functional Description
The ’ACT823 consists of nine D-type edge-triggered flip-
flops. These have TRI-STATE outputs for bus systems or-
ganized with inputs and outputs on opposite sides. The buff-
ered clock (CP) and buffered Output Enable (OE) are com-
mon to all flip-flops. The flip-flops will store the state of their
individual D inputs that meet the setup and hold time re-
quirements on the LOW-to-HIGH CP transition. With OE
LOW, the contents of the flip-flops are available at the out-
puts. When 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. In addition to the Clock and Output
Enable pins, there are Clear (CLR) and Clock Enable (EN)
pins. These devices are ideal for parity bus interfacing in
high performance systems.
When CLR is LOW and OE is LOW, the outputs are LOW.
When CLR is HIGH, data can be entered into the flip-flops.
When EN is LOW, data on the inputs is transferred to the
outputs on the LOW-to-HIGH clock transition. When the EN
is HIGH, the outputs do not change state, regardless of the
data or clock input transitions.
