OL7272
Industrial 30 Volt 4-Channel Differential Power Linedriver - Short Circuit Proof -
Applications
Industrial encoder interfacing
Industrial sensor interfacing
Proximity switches
Industrial controllers PLC
Light barriers
Features
Max. voltage range from 4,5 V – 36 V
Short circuit proof tri-state outputs drive
up to 120mA sink / source
Operating frequency up to 4 MHz
Pin compatible with ET7272
Dynamic peak current up to 1,5 Amp.
High impedance CMOS / TTL compatible
buffered inputs with hysteresis
Outputs RS422A compatible
Small package TSSOP (OL2068) available
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.

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