Order this document by ULN2068/D The ULN2068B is a high–voltage, high–current quad Darlington switch array designed for high current loads, both resistive and reactive, up to 300 W. It is intended for interfacing between low level (TTL, DTL, LS and 5.0 V CMOS) logic families and peripheral loads such as relays, solenoids, dc and stepping motors, multiplexer LED and incandescent displays, heaters, or other high voltage, high current loads. The Motorola ULN2068B is specified with minimum guaranteed breakdown of 50 V and is 100% tested for safe area using an inductive load. It includes integral transient suppression diodes. Use of a predriver stage reduces input current while still allowing the device to switch 1.5 Amps. It is supplied in an improved 16–Pin plastic DIP package with heat sink contact tabs (Pins 4, 5, 12 and 13). A copper alloy lead frame allows maximum power dissipation using standard cooling techniques. The use of the contact tab lead frame facilitates attachment of a DIP heat sink while permitting the use of standard layout and mounting practices. • TTL, DTL, LS, CMOS Compatible Inputs • • • • • QUAD 1.5 A DARLINGTON SWITCH SEMICONDUCTOR TECHNICAL DATA 1.5 A Maximum Output Current B SUFFIX PLASTIC PACKAGE CASE 648C Low Input Current Internal Freewheeling Clamp Diodes 100% Inductive Load Tested Heat Tab Copper Alloy Lead Frame for Increased Dissipation MAXIMUM RATINGS (TA = 25°C and ratings apply to any one device in the PIN CONNECTIONS package, unless otherwise noted) Rating Symbol Value Unit Output Voltage VO 50 V Input Voltage (Note 1) VI 15 V Supply Voltage VS 10 Collector Current (Note 2) IC Input Current (Note 3) II Operating Ambient Temperature Range Storage Temperature Range Junction Temperature K 1 16 C V C 2 15 B 1.75 A B 3 14 VS 25 mA 4 13 Gnd 0 to +70 °C Gnd TA Tstg –55 to +150 °C Gnd 5 12 Gnd TJ 150 °C B 6 11 B NC 7 10 C NOTES: 1.
