VOL vs. IOL
The I
2C specification mandates a maximum VIL (IOL of
3mA) of VCC 0.3 and a maximum VOL of 0.4V. If there
is a master on the A port of an I
2C translator with a VCC
of 1.65V and a slave on the I
2C translator B port with a
VCC of 3.3V, the maximum VIL of the master is (1.65V x
0.3) 495mV. The slave could legally transmit a valid
logic LOW of 0.4V to the master.
If the I
2C translator’s channel resistance is too high, the
voltage drop across the translator could present a VIL to
the master greater than 495mV. To complicate matters,
the I
2C specification states that 6mA of IOL is
recommended
for
bus
capacitances
approaching
400pF. More IOL increases the voltage drop across the
I
2C translator. The I2C application benefits when I2C
translators exhibit low VOL performance. Figure 6
depicts typical FXMAR2102 VOL performance vs. the
competition, given a 0.4V VIL.
