74ALVT16823

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

应用领域

The 74ALVT16823 is an 18-bit positive-edge triggered D-type flip-flop with 3-state outputs, reset and enable.

The device can be used as two 9-bit flip-flops or one 18-bit flip-flop. The device features clock (nCP), clock enable (nCE), master reset (nMR) and output enable (nOE, inputs each controlling 9-bits. When nCE is LOW, the 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 clock (nCP) transition. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Operation of the nOE input does not affect the state of the flip-flops. A LOW on nMR will reset the flip-flops LOW. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs
