7.4 Comparison of PCA9601/PCA9600 and P82B96
) range:

):
The PCA9601 is a direct upgrade of the P82B96 with the significant differences
summarized in
Fast-mode Plus devices on the SX/SY sides.
When the device driving the PCA9601/PCA9600 is an I
the PCA9601 is an improvement on the P82B96 as shown in
exceptions however, and if the device driving the bus buffer is not I
(e.g., you need to use the micro already in the system and bit-bang using two GPIO pins)
then here are some considerations that would point to using the P82B96 instead:
•
•
IL
When the pull-up must be the weakest one possible. The spec is 200 μA for P82B96,
but it typically works even below that. And if designing for a temperature range −40 °C
up to +60 °C, then the driver when sinking 200 μA only needs to drive a guaranteed
low of 0.55 V. For the PCA9601/PCA9600, over that same temperature range and
when sinking 1.3 mA (at −40 °C), the device driving the bus buffer must provide the
required low of 0.425 V.
When the lower operating temperature range is restricted (say 0 °C). The P82B96
larger SX voltage levels then make a better typical match with the driver, even when
the supply is as low as 3.3 V.
For an I
low that is below 0.83 V. P82B96 guarantees that with a 200 μA pull-up.
