LB1275

Ordering number:ENN790C Monolithic Digital IC LB1275 7-Unit, Darlington Transistor Array 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.
