Overview
TECHNICAL DATA IN74ACT21 Dual 4-Input AND Gate High-Speed Silicon-Gate CMOS The IN74ACT21 is identical in pinout to the LS/ALS21, HC/HCT21.
The IN74ACT21 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; 0.
