TECHNICAL DATA
Octal 3-State
Noninverting D Flip-Flop
High-Speed Silicon-Gate CMOS
IN74ACT374
The IN74ACT374 is identical in pinout to the LS/ALS374,
HC/HCT374. The IN74ACT374 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; 0.1 µA @ 25°C
Outputs Source/Sink 24 mA

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND(VIN or
VOUT)VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
