NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUMRATINGS
may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions
above those indicated in the operational sections of the specification is not
implied. Exposure to absolute maximumrating conditions for extended
periods may affect reliability.
2. V
TERM
must not exceed V
CC
+ 10% for more than 25% of the cycle time or 10ns
maximum and is limted to < 20mA for the period of V
TERM
> V
CC
+ 10%.
NOTES:
1. V
IL
(mn.) = -1.5V for pulse width less than 20ns.
2. V
TERM
must not exceed Vcc + 0.3V.
NOTES:
1. This is the parameter T
A
. This is the "instant on" case temperature.
2. Industrial temperature: for specific speeds, packages and powers contact your
sales office.
