Conditions/Comments
This is a measure of the minimum and maximum
drive capability of the output amplifier.
VDD = 5 V.
VDD = 3 V.
Coming out of power-down mode. VDD = 5 V.
Coming out of power-down mode. VDD = 3.3 V.
VIN = 0 V to VDD.
All digital inputs.
Input filtering suppresses noise spikes of less
than 50 ns.
Edge triggered input.
ISOURCE = ISINK = 200 µA.
IOL = 3 mA.
VOH = 5 V.
IOUT = 4 mA.
Fast Mode I2C. See Figure 2.
