Sanyo LB1274 Specifications

Ordering number:ENN535C

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 printers, relays, and lamps. Protective diodes guard against negative inputs. Thus it has advantages when designing circuits to drive printer-calculators that use display tubes, cash registers, and the like.

Features

•Ideal for 18-digit printers (because it has 6 units).

•Protective diodes are incorporated against negative inputs (VIN=–40 to +20V).

•Ideal for printers, with 85-mA load current (IOUT max =100mA DC).

•Spark-killer diodes accommodate L-loads.
