Output A
Output A-
The OL2068 is an industrial power line
driver and contains four identical short cir-
cuit proof differential line drivers up to 30
Volts driver supply with a joint enable func-
tion. An internal 5 V power supply is used
as reference and supply voltage for the
circuitry and is able to supply max. 5mA
for external 5V components like a sensor
or a constant current source for an LED.
The very small outline TSSOP package
gives excellent thermal power dissipation,
thus the usage in space limited applica-
tions is easy.

NOTE:Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability (eq. hot
carrier degradation).
