NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS 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 this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. V
TERM
must not exceed Vcc + 10% for more than 25%of the cycle time or 10 ns
maximum, and is limited to < 20mA for the period of V
TERM
> Vcc +10%.
3. V
TERM
= 5.5V.
NOTES:
1. This parameter is determined by device characterization but is not production
tested.
2. 3dV references the interpolated capacitance when the input and output signals
switch from 0V to 3V and from 3V to 0V.
NOTES:
1. This is the parameter T
A
.
2. Industrial temperature: for specific speeds, packages and powers contact your
sales office.
NOTES:
1. V
IL
(min.) > -1.5V for pulse width less than 10ns.
2. V
TERM
must not exceed Vcc + 10%.
NOTES:
1. At Vcc < 2.0V input leakages are undefined.
