Overview
The LB1731 is a 4-channel high-voltage current sink output driver. Inputs are active-low CMOS/TTL logic-level, and outputs are high-voltage open-collector NPN Darlington pairs.
Each driver in the LB1731 sinks up to 1.5A and withstands collector voltages of up to 85V. The LB1731 is available in a 16-pin DIP package.

FEATUREs
• For independent high-voltage high-current drivers.
• Output clamp diodes.
• Input protection diodes.
• 5V CMOS- and TTL-compatible logic-level inputs.
