Characteristic
Supply voltage 3.3 V
Input high voltage
Input low voltage
Input leakage current, V_IN = supply voltage
Tri-state (high impedance off state) leakage current, V_IN = supply voltage
Signal low input current, V_IL = 0.4 V²
Signal high input current, V_IH = 2.0 V²
Output high voltage, I_OH = –2 mA,
except open drain pins
Output low voltage, I_OL= 3.2 mA
Notes: 1. See Figure 6 for undershoot and overshoot voltages.
2. Not tested. Guaranteed by design.
