3-V 20-bit Bus Interface Flip Flops with 3-state Outputs
ADE-205-186A (Z) 2nd.
Edition September 1997 Description
The HD74ALVCH162821 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 ten outputs in either a normal logic state (high or low level) or a high impedance state.
In the high impedance state, the outputs neither load nor drive the bus lines significantly.
The high impedance state and increased drive provide the capability to drive bus li...
