PARAMETER
PARAMETER
This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down
and pull-up resistors add +/- 50uA per-pin (typical).
This is the total 5.5V input leakage for the entire device.
XI can optionally be driven from a 25MHz single-ended clock oscillator.
IEEE 802.ab Test Mode 1
From 1/2 of average V
