NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
= 5V, T
= 25
°
C.
3. Not more than one output should be shorted at a time. For testing I
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
tests should be performed last.
4. Due to test equipment limitations, actual test conditions are V
= 1.8V and V
= 1.3V for the B side.
5. For B port input voltage between 3 and 5 volts I
IH
will be greater than 100
μ
A, but the parts will continue to function normally.
