Note

Absolute maximum ratings are those values beyond

which the safety of the device cannot be guaranteed They

are not meant to imply that the device should be operated at

these limits

Note

An asterisk following a parameter’s symbol indicates that the param-

eter has been characterized but not tested

Note

All specifications in this datasheet are valid only if the mandatory

isolation is employed and all differential signals are taken to exist at the AUI

side of the pulse transformer

Note 1

This measurement was made while the DP83910A was undergoing transmission reception and collision detection Also this value was not measured

instantaneously but averaged over a span of several milliseconds (VIN e 24V or 04V and Io e 0 mA)

Note 2

This measurement was made while the DP83910A was sitting idle with TXE low Also this value was not measured instantaneously but averaged over a

span of several milliseconds (VIN e 24V or 04V and Io e 0 mA)

Note 3

This parameter is guaranteed by design and is not tested
