Overview
This LB1275, 7-unit Darlington transistor array using NPN
transistors, is specially designed for printer driver , lamp or
relay driver.
Package Dimensions
unit:mm
3006C-DIP16
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 (I
OUT
max
=100mA DC).
