ULN2068
Quad 1.5 A Sinking High
Current Switch
The ULN2068B is a high鈥搗oltage, high鈥揷urrent 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鈥揚in 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.
