Monolithic Digital IC
LB1274
6-Unit, Darlington Transistor Array
Overview
Circuit structure of this IC is a 6-unit Darlington transistor
array with NPN transistors. The IC is ideal for driving print-
ers, relays, and lamps. Protective diodes guard against nega-
www.DataSheett4ivUe.cionmputs. Thus it has advantages when designing circuits
to drive printer-calculators that use display tubes, cash reg-
isters, and the like.

Features
• Ideal for 18-digit printers (because it has 6 units).
• Protective diodes are incorporated against negative in-
puts (VIN=–40 to +20V).
• Ideal for printers, with 85-mA load current (IOUT max
=100mA DC).
• Spark-killer diodes accommodate L-loads.
