Od: open drain output, OT: 3-state output, 5Tr: 5V Tolerant, Drive: driving capability
Note) VC1 has no built-in pull up resistor. Pull up the pins externally as necessary.
The tolerant attribute is an attribute of the input buffer, output buffer that can become the high-impedance
state, and bi-directional buffer, and indicates it can endure the 5V signal.
