Note 16:
This is the static current consumption from V
CCA
for the part common to the channels.
Note 17:
Only I
CCBTOTAL
for DIR1=DIR2=DIR3=H and I
CCATOTAL
for DIR1=DIR2=DIR3=L will be tested in production.
Calculation example:
assuming DIR1=H, DIR2=L, DIR3=L, then the typical I
CCB
current will be:
I
CCBTOTAL
= I

The typical I
CCA
current is:
I
CCATOTAL
= I
A
= 90 μA.
Note 18:
This is the time it takes either to switch the level shifter on or off, or the time it takes to turn the latch by-pass on/off.
Note 19:
This is the time it takes to switch the direction of the level shifter. After this time a signal can be applied on the new input. For the B
→
A direction, if EN2=1,
the latch set-up time has to be considered separately.
Note 20:
The output voltage changes slightly with line voltage. An increase in the line voltage results in a slight increase in the output voltage and vice versa.
Note 21:
The output voltage changes slightly with load current. An increase in the load current results in a slight decrease in the output voltage and vice versa.
Note 22:
Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its normal value. This specification does not apply
for input voltages below 2.7V.
Note 23:
Turn-on time is that between the enable input just exceeding V
IH
and the output voltage just reaching 95% of its nominal value.
Note 24:
Range of capacitor values for which the device will remain stable. This electrical specification is guaranteed by design.
Note 25:
Range of capacitor ESR values for which the device will remain stable. This electrical specification is guaranteed by design.
Note 26:
The built-in thermal shut-down of the LDO is also used to put all Ai and Bi outputs in tristate mode.
Note 27:
Additional information on lead temperature and pad temperature can be found in National Semiconductor Application Note (AN-1112).
Note 28:
Unused inputs must be terminated.
Note 29:
This electrical specification is guaranteed by design.
