2.
Measured between pins 1 through 8 shorted together and pins 9 through 16 shorted together.
3.
Measured between pins 9 and 10 or 11 and 12 shorted together, and pins 9 through 16 shorted together.
4.
Measured between pins 9 and 10 shorted together, and pins 11 and 12 shorted together.
5.
The t
plh
propagation delay is measured from the 6.5mA point on the trailing edge of the input pulse to the 1.5V point on the trailing edge of the output pulse.
6.
The t
phl
propagation delay is measured from the 6.5mA point on the leading edge of the input pulse to the 1.5V point on the leading edge of the output pulse.
7.
CM
h
is the max. tolerable common mode transient to assure that the output will remain in a high logic state (i.e. V
O
>
2.0V).
8.
CM
l
is the max. tolerable common mode transient to assure that the output will remain in a low logic state (i.e. V
O
<
0.8V).
9.
It is essential that a bypass capacitor (.01 to 0.1
μ
F ceramic) be connected from pin 1 to pin 4.
