74ALVCH16823: 18-bit bus-interface D-type flip-flop with reset and enable (3-State) (Based on PIP 74ALVCH16823)

The 74ALVCH16823 is a 18-bit edge-triggered flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. Incorporates bushold data inputs which eliminate the need for external pull-up resistors to hold unused inputs. The74ALVCH16823 consists of two sections of nine edge-triggered flip-flops. A clock (CP) input, an output-enable (OE) input, a Master reset (MR) input and a clock-enable (CE) input are provided for each total 9-bit section.

With the clock-enable (CE) input LOW, the D-type flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH CP transition. Taking CE HIGH disables the clock buffer, thus latching the outputs. Taking the Master reset (MR) input LOW causes all the Q outputs to go LOW independently of the clock.

When OE is LOW, the contents of the flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of flip-flops.

Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
