TECHNICAL DATA
www.DataSheet4U.com
Octal 3-State
Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
KK74ACT574
The KK74ACT574 is identical in pinout to the LS/ALS574,
HC/HCT574. The KK74ACT574 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 Range: 4.5 to 5.5 V
Low Input Current: 1.0 µA; 0.1 µA @ 25°C
Outputs Source/Sink 24 mA
