High Temperature Operation
Due to power dissipation and instantaneous output short
circuit current levels at V
be operated at +125°C with V
At V
at +125°C, while driving a 100’, double terminated, CAT 5
cable at 20Mbps, without triggering the thermal SHDN
circuit.

Low Power Shutdown Mode
These BiCMOS transmitters all use a fraction of the power
required by their bipolar counterparts, but they also include a
shutdown feature that reduces the already low quiescent I
to a 1µA trickle. These devices enter shutdown whenever
the driver disables (DE = GND).
