TECHNICAL DATA
Octal 3-State
Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
IN74HCT574A
The IN74HCT574A is identical in pinout to the LS/ALS574. This
device 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
