HD74ALVCH162374
16-bit Edge triggered D-type Flip Flops with 3-state Outputs
ADE-205-180B (Z) Preliminary 3rd. Edition October 1997 Description
The HD74ALVCH162374 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit flip flops or one 16-bit flip flop. On the positive transition of the clock (CLK) input, the Q outputs of the flip flop take on the logic levels set up at the data (D) inputs. The output enable ( OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high impedance state. In the high impedance state, the outputs neither load nor drive the bus lines significantly.
