TECHNICAL DATA
Octal 3-State
Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
KK74HCT374A
The KK74HCT374A is identical in pinout to the LS/ALS374.
The KK74HCT374A may be used as a level converter for interfacing
TTL or NMOS outputs to High-Speed CMOS inputs.
Data meeting the setup and hold 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, the 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
