Overview
This LB1275, 7-unit Darlington transistor array using NPN transistors, is specially designed for printer driver, lamp or relay driver.
Protector diodes against negative input are used by which it is easy to design drive circuits of a calculator with a printer using indicator or a cash register.
   
Features
• 7-unit version (DIP-16) or LB1274 (6-unit DIP-14).
• Protector diodes against negative input (VIN=–40 to +20V).
• Spark killer diodes for inductive load.
• Suitable for 85mA type printer mechanism (IOUT max = 100mA DC).
