SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
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.
