TECHNICAL DATA IN74ACT574 Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The IN74ACT574 is identical in pinout to the LS/ALS574, HC/HCT574.
The IN74ACT574 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
Data meeting the setup time is clocked to the outputs with the rising edge of the Clock.
The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, all device outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled.
• TTL/NMOS Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage...
