Ordering number:ENN535C Monolithic Digital IC LB1274 6-Unit, Darlington Transistor Array Overview Package Dimensions Circuit structure of this IC is a 6-unit Darlington transistor unit:mm array with NPN transistors. The IC is ideal for driving print- 3004A-DIP14TD ers, relays, and lamps. Protective diodes guard against nega- [LB1274] tive inputs. Thus it has advantages when designing circuits 14 to drive printer-calculators that use display tubes, cash reg- isters, and the like. Features 1 • Ideal for 18-digit printers (because it has 6 units). 2.0 19.0 • 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. 2.54 1.8 0.5 1.3 SAN
