Voltages are measured from the local ground potential, unless otherwise specified.
Typicals are at TA=25°C and represent most likely parametric norm.
The maximum allowable power dissipation at any temperature is PD = (TJmax - TA) / QJA.
Timing specifications are tested at the TTL logic levels, VIL=0.4V for a falling edge and VIH=2.4V for a rising
edge. TRI-STATE output voltage is forced to 1.4V.

CAPACITANCE T
The input capacitance of a port is measured at the connector pins.
All leakage currents are measured with all pins in high impedance.
