DESCRIPTION
The 74HC1G/HCT1G02 is a high speed Si-gate CMOS
device.
The 74HC1G/HCT1G02 provides the 2-input NOR
function. The standard output currents are half the values
compared to the 74HC/HCT02.

Notes
1. C_PD is used to determine the dynamic power dissipation P_D (µW).
P_D = C_PD × V_CC2 × f_i + ∑ (C_L × V_CC2 × f_o) where:
f_i = input frequency in MHz;
f_o = output frequency in MHz;
C_L = output load capacitance in pF;
V_CC = supply voltage in Volts;
∑ (C_L × V_CC2 × f_o) = sum of outputs.
2. For HC1G the condition is V_I = GND to V_CC.
For HCT1G the condition is V_I = GND to V_CC − 1.5 V.
