TECHNICAL DATA
Dual 4-Input NAND Gate
High-Performance Silicon-Gate CMOS
KK74HCT20A
The KK74HCT20A is identical in pinout to the LS/ALS20. The
KK74HCT20A may be used as a level converter for interfacing TTL or
NMOS outputs to High-Speed CMOS inputs.
• 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
• High Noise Immunity Characteristic of CMOS Devices
