The leakage currents are generally very small, <1nA. The value given here, 1 µA, is a maximum that can occur after an Electrostatic Stress on the pin. 2. V> Vdd3 for 3.3V buffers. 3. Human Body Model LVTTL & LVCMOS DC Input Specification 2.7V <Vdd3 <3.6V Note: 1. Takes into account 200mV voltage drop in both supply lines. 2.
