Dual 4-Input NAND Gate
High-Performance Silicon-Gate CMOS

The SL74HCT20 is identical in pinout to the LS/ALS20. The SL74HCT20 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
