DC Specifications

Note 5-5

This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down and pull-up

resistors add +/- 50uA per-pin (typical).

Note 5-6

XI can optionally be driven from a 25MHz single-ended clock oscillator.

Note 5-7

IEEE 802.ab Test Mode 1

Note 5-8

From 1/2 of average VOP, Test Mode 1
