High Temperature Operation
Due to power dissipation and instantaneous output short
circuit current levels at VCC = 5V, these transmitters may not
be operated at +125°C with VCC > 3.6V.
At VCC = 3.6V, even the SOT-23 versions may be operated
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 ICC
to a 1A trickle. These devices enter shutdown whenever
the driver disables (DE = GND).
Typical Performance Curves VCC = VL = 3.3V, TA = +25°C; Unless Otherwise Specified
