Note 3:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test condition, see Electrical
Characteristics tables.
Note 4:
All voltages are with respect to the potential at the GND pin.
Note 5:
The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using the formula
P = (T
J
T
A
)/
θ
JA
,
Where T
J
is the junction temperature, T
A
is the ambient temperature, and
θ
JA
is the junction-to-ambient thermal resistance. The 360 mW rating appearing under
Absolute Maximum Ratings results from substituting the Absolute Maximum junction temperature, 150C, for T
J
, 85C for T
A
, and 180C/W for
θ
JA
. More power can
be dissipated safely at ambient temperatures below 85C. The thermal resistance can be better or worse than 180C/W depending on board layout. Larger copper
planes and thermal vias should be used to conduct heat away from the micro SMD solder bumps.
Note 6:
The Human Body Model is 100 pF discharged through 1.5 k
resistor into each pin.
Note 7:
V
CCB
can be supplied from an external voltage source in the range of 1.65V to 3.6V, as long as both V
BAT
and V
CCB
are connected to the external source.
Only the LDO quiescent current (see DC electrical specifications) will add to the level-shifter current consumption. This Operating Rating does not imply guaranteed
performance. For guaranteed performance limits and associated test conditions, see Electrical Characteristics tables.
Note 8:
Like the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 220 mW rating
appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125C, for T
J
, 85C for T
A
, and 180C/W for
θ
JA
into
(1) above. More power can be dissipated at ambient temperatures below 85C. The thermal resistance can be better or worse than 180C/W depending on board
layout. Larger copper planes and thermal vias should be used to conduct heat away from the micro SMD solder bumps.
Note 9:
All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production with T
J
= 25C or correlated using
Statistical Quality Control (SQC) methods. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations
and applying statistical process control.
Note 10:
The target output voltage, which is labeled V
OUT(target)
, is the desired or ideal output voltage. The nominal output voltage, which is labeled V
OUT(nom)
, is
the output voltage measured with the input 0.5V above V
OUT(target)
and a 1 mA load.
Note 11:
Input leakage current for pins DIRi, EN1, EN2.
Note 12:
Input leakage current for pins Bi, LatchClk.
Note 13:
This is the static current consumption from V
CCB
for channel (i) when DIRi=H (A
→
B direction).
Note 14:
This is the static current consumption from V
CCB
for channel (i) when DIRi=L (B
→
A direction).
Note 15:
This is the static current consumption from V
CCB
for the part common to the channels.
