Transistor Arrays
GENERAL DESCRIPTION
The XR-2011/2012/2013/2014 are high-
voltage, highcurrent Darlington transistor arrays consisting of seven silicon NPN Darlington pairs on a common monolithic substrate.
All units feature open collector outputs and integral protection diodes for driving inductive loads.
Peak inrush currents of up to 750 mA are allowed, which makes the arrays ideal for driving tungsten filament lamps.
The outputs may be paralleled to achieve higher load current capability although each driver has a maximum continuous collector current rating of 600 mAo The arrays are directly price competitive with discrete transisto...
