Dual 4-Input AND Gate
TECHNICAL DATA
KK74HC21A
The KK74HC21A is high-speed Si-gate CMOS device and is pin
compatible with pullup resistors with low power Schottky TTL (LSTTL).
The device provide the Dual 4-input AND function.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
