High impedance CMOS / TTL compatible buffered inputs with hysteresis Outputs RS422A compatible Small package TSSOP (OL2068) available Line voltage in Voltage regulator 5V , 5mA out General Description The OL7272 is an industrial power linedriver and contains four identical short circuit proof differential linedrivers up to 30 Volts driver supply with a joint enable function. At overload there is a thermal shutdown feature which can be disabled by the user. The high data rate and immunity to cable inductance and capacitance makes an ideal linedriver. The small outline SOP package gives excellent thermal power dissipation, thus the usage in space limited applications is easy.

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). 1 2 3 4 5 Look at over-temperature protection Table 3 For surface mounting plastic packages. Valid for normal function. To disable automatic thermal shutdown, this pin should be set to 7,5 – 12 Volt. Limited by power dissipation. Driving capability at elevated temperatures will be limited by total package power dissipation. Special packages up to 125°C can be supplied.
