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.
