HD74LV574A
Octal Edge-Triggered D-type Flip-Flops with 3-state Outputs
ADE-205-280 (Z) 1st Edition April 1999 Description
The HD74LV574A has eight edge-triggered D-type flip-flops with three-state outputs in a 20-pin package.
Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive going transitions of the clock input.
When the clock input goes low, data at the D inputs will be retained at the outputs until clock input returns high again.
When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
