KODENSHI KK74ACT244DW

TECHNICAL DATA
KK74ACT244
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Speed Silicon-Gate CMOS
The KK74ACT244 is identical in pinout to the LS/ALS244,
HC/HCT244. The KK74ACT244 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
This octal noninverting buffer/line driver/line receiver is designed to
be used with 3-state memory address drivers, clock drivers, and other
bus-oriented systems. The device has noninverting outputs and two
active-low output enables.
• 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.
