QUAD HIGH-CURRENT,  
HIGH-VOLTAGE SOURCE DRIVER  
Capable of driving loads to 4 A at supply voltages to 60 V (induc-  
tive loads to 35 V), the UDN2944W is a quad high-current, high-  
voltage source driver. Each of the four power drivers can provide  
space- and cost-saving interface between low-level signal-processing  
circuits and high-power loads in harsh environments.  
VS  
Individual supply lines have been provided for each pair of drivers  
so that different supplies can be used to drive multiple loads. The  
controlling inputs are TTL or CMOS compatible. The outputs include  
transient-suppression diodes for inductive loads.  
This quad Darlington array is designed to serve as an interface  
between low-level circuitry and peripheral-power loads such as sole-  
noids, motors, incandescent displays, heaters, and similar loads of up to  
240 W per channel. The UDN2944W is an ideal complement to the  
UDN2878W quad 4 A sink driver.  
Dwg. No. A-13,054  
For maximum power-handling capability, the UDN2944W driver  
is supplied in a 12-pin single in-line, power-tab package that allows  
efficient attachment of an external heat sink for maximum allowable  
package power dissipation. An external heat sink is usually required  
for proper operation of this device. The tab is at ground potential and  
needs no insulation.
