Quad 2-Input NOR GateSpecificationsThis NOR gate utilizes advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with low power consumption of standard CMOS integrated circuits. All gates have buffered outputs, providing high noise immunity and the ability to drive 10 LS-TTL loads. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground. Typical propagation delay: 8ns Wide power supply range: 2-6V Low quiescent supply current: 20uA max Low input current: 1uA max High output current 4mA minimum
