The 74hc10 chip is a 3-input three-and-not gate circuit. It is characterized by transmission delay time of 8ns, wide power supply range, 2 ~ 6v, low static current, 20uA (maximum), low input current, 1uA (maximum), and fan out 10Is - TTL load. The logic function is that the three inputs are high and the output is low. Otherwise the output is high.
