Octal High-Voltage, Current-Source Output Driver

Overview

The LB1745 is an octal high-voltage current source output

driver with active-low inputs. High output drive capability

for low input current is achieved with NPN Darlington-

pair output drivers.

The LA1745 sources up to 500mA from each driver at sup-

ply voltages of up to 50V. It is available in 18-pin plastic

DIPs.
