Functional Description

The ’ACT825 consists of eight D-type edge-triggered

flip-flops. These devices have TRI-STATE^®outputs for bus

systems, organized in a broadside pinning. In addition to the

clock and output enable pins, 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 time requirements on the

LOW-to-HIGH CP transition. With OE₁, OE₂and OE₃LOW,

the contents of the flip-flops are available at the outputs.

When one of OE₁, OE₂or OE₃is HIGH, the outputs go to the

high impedance state.

Operation of the OE input does not affect the state of the

flip-flops. The ’ACT825 has Clear (CLR) and Clock Enable

(EN) pins. These pins 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 EN is

HIGH, the outputs do not change state, regardless of the

data or clock input transitions.
