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.
Features
• Eight independent Darlington-pair driver circuits.
• High-voltage, high-current source.
• Output clamp diodes.
• Input protection diodes.
