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 Darlingtonpair output drivers.
The LA1745 sources up to 500mA from each driver at supply 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.
