The 74HC2G32; 74HCT2G32 is a dual 2-input OR gate. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of
VCC.
The 74HC1G00; 74HCT1G00 is a single 2-input NAND gate. Inputs include clamp diodes
that enable the use of current limiting resistors to interface inputs to voltages in excess of
VCC.
