Table 1–4 lists supply current specifications for V

supply current estimates for the remaining power supplies.

I/O Pin Leakage Current

Table 1–5 defines HardCopy III I/O pin leakage current specifications.

On-Chip Termination (OCT) Specifications

If OCT calibration is enabled, calibration is automatically performed at power up for

I/Os connected to the calibration block. Table 1–6 lists the HardCopy III OCT

calibration block accuracy specifications.

(2) The 10 mA I/O leakage current limit is applicable when the internal clamping diode is off. A higher current is

observed when the diode is on.
