Nexperia B.V. 20-bit bus-interface D-type flip-flop; positive-edge trigger; 3-state 74ALVCH16821DGG,11

The 74ALVCH16821 has two 10-bit, edge triggered registers, with each register coupled to a 3-state output buffer. The two sections of each register are controlled independently by the clock (nCP) and output enable nOEcontrol gates.

Each register is fully edge triggered. The state of each nDn input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop’s nQn output.

When nOEis LOW, the data in the register appears at the outputs. When nOEis HIGH, the outputs are in high impedance OFF state. Operation of the nOEinput does not affect the state of the flip-flops.

The 74ALVCH16821 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
