Note 1: “Absolute Maximum Ratings” are those 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. The table of “Electrical Characteristics” provides conditions for actual device operation.

Note 3: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified.

Note 4: Only one output should be shorted at a time, and duration of the short should not exceed one second.

Note 5: Referenced to appropriate signal ground. Do not exceed maximum power dissipation of package.

Note 6: Input waveforms shall have a rise/fall time of 3 ns. Propagation delays are measured with a single output switching.

Note 8: The parameter is tested using TDR techniques described in 1194.0 BTL backplane Design Guide.

Note 9: This parameter is tested during device characterization. The measurement revealed that the part will reject 1 ns pulse widths.

Note 10: Futurebus+ transceivers are required to limit bus signal rise and fall times to no faster than 0.5 V/ns, measured between 1.3V and 1.8V (approximately 20%

to 80% of nominal voltage swing). The rise and fall times are measured with a transceiver loading equivalent to 12.5

Ω tied to +2.1V DC.
