ULN2001D

The ULN2001D is designed as one kind of high voltage,high current darlington arrays which contains seven open collector darlington pairs with common emitters. Each channel rated at 500mAand can withstand peak currents of 600mA.Suppressiondiodesare included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.

ULN2001D has seven features. (1)Seven darlingtons per package. (2)Output current 500mA per driver (600mA peak). (3)Output voltage 50V. (4)Integrated suppression diodes for inductive loads. (5)Outputs can be paralleled for higher current. (6)TTL/CMOS/PMOS/DTL compatible inputs. (7)Inputs pinned opposite outputs to simplify layout. Those are all the main features.

Some absolute maximum ratings of ULN2001D have been concluded into several points as follow. (1)Its output voltage would be 50V. (2)Its input voltage would be 30V. (3)Its continuous collector current would be 500mA. (4)Its continuous base current would be 25mA. (5)Its operating ambient temperature range would be from -20°C to 85°C. (6)Its storage temperature range would be from -55°C to 150°C. (7)Its junction temperature would be 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of ULN2001D are concluded as follow. (1)Its output leakage current would be max 50uA at Vce=50V and would be max 100uA at Tamb=70°C and Vce=50V. (2)Its collector to emitter saturation voltage would be typ 0.9V and max 1.1V at Ic=100mA and Ib=250uA and it would be typ 1.1V and max 1.3V at Ic=200mA and Ib=350uA and it would be typ 1.3V and max 1.6V at Ic=350mA and Ib=500uA. (3)Its input current would be min 50uA and typ 65uA. (4)Its DC forward current gain would be min 1000. (5)Its input capacitance would be typ 15pF and max 25pF. And so on.
