Notes:
1. Minimum DC input is –0.3V. During transactions, the inputs may undershoot to –2.0V or overshoot to 7.0V for input currents less then 100 mA and periods shorter
than 20 ns.
2. The Voltage on any input or I/O pin cannot exceed the power pin during power-up.
3. The I_OH parameter refers to high-level TTL output current; the I_OL parameter refers to low-level TTL output current.
