TECHNICAL DATA

Octal 3-State Noninverting D Flip-Flop

IN74ALS574

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
