TECHNICAL DATA
IN74ALS574
Octal 3-State Noninverting D Flip-Flop
The device is comprised of eight edge-triggered D-Type flip-flops. On the positive transition of the clock, the Q outputs will be set to the logic states that were set up at the D inputs. A buffered output control 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. · Switching specifications at 50 pF · Switching specifications guaranteed over full temperature and VCC range · TRI-STATE buffer-type outputs drive bus lines directly
