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

VDD settles to within 10% of its final voltage level

VDD = 3.3 V, VIH = VDD, and VIL = GND

VDD = 5 V, VIH = VDD, and VIL = GND
