C-bus and SMBus voltage-level translator
be able to sink the total current from both pull-up resistors. When selecting the minimum
resistor value in Table 11
, Table 12 or Table 13, the drive current strength that should be
chosen should be the lowest drive current seen in the application and account for any
drive strength current scaling with output voltage. For the GTL devices, the resistance
table should be recalculated to account for the difference in ON resistance and bias
voltage limitations between V
CC(B)
and V
CC(A)
.
