74ALVCH16823DGG

18-bit bus-interface D-type flip-flop with reset and enable; 3-state

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. The 74ALVCH16823 consists of two sections of nine edge-triggered flip-flops. A clock (nCP) input, an output-enable (nOE) input, a master reset (nMR) input and a clock-enable (nCE) input are provided for each total 9-bit section.

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

When nOE is LOW, the contents of the flip-flops are available at the outputs. When the nOE is HIGH, the outputs go to the high impedance OFF-state. Operation of the nOE 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.

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
