1. Insensitive to sequence of VCC, VCCAUX and VCCIO. However, assumes monotonic rise/fall rates for VCC, VCCAUX and VCCIO.
2. 0 ≤ VCC ≤ VCC (MAX), 0 ≤ VCCIO ≤ VCCIO (MAX) or 0 ≤ VCCAUX ≤ VCCAUX (MAX).
3. IDK is additive to IPU, IPW or IBH.
4. LVCMOS and LVTTL only.

1. Input or I/O leakage current is measured with the pin configured as an input or as an I/O with the output driver tri-stated. It is not measured
with the output driver active. Bus maintenance circuits are disabled.
2. TA 25oC, f = 1.0MHz.
