HD74ALVCH16821 Datasheet (Hitachi Semiconductor) - 3.3-V 20-bit Bus Interface Flip Flops with 3-state Outputs

HD74ALVCH16821, 3.3-V 20-bit Bus Interface Flip Flops with 3-state Outputs

The HD74ALVCH16821 can be used as two 10-bit flip flops or one 20-bit flip flop.

The 20 flip flops are edge triggered D-type flip flops.

On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs.

A buffered output enable ( OE ) input can be used to place the
