The ULN2001, ULN2002, ULN2003 and ULN 2004 are high-voltage, high-current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel is rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout

The ULN2003LV is a low-voltage and low power 1? 7-Channel High Current Sink Drivers upgrade of TI?s popular ULN2003 family of 7-channel ? Supports up to 8V Ouput Pullup Voltage Darlington transistor array. The ULN2003LV sink ? Supports a Wide Range of 3V-to-5V Relay and driver features 7 low output impedance drivers to Inductive Coils support low voltage relay and inductive coil applications. The low impedance drivers minimize on- ? Low Output VOL of 0.4V (Typical) With chip power dissipation; up to 5 times lower for typical ? 100mA (Typical) Current Sink per Channel at 3V relays. The ULN2003LV driver is pin-to-pin 3.3V Logic Input(1) compatible with ULN2003 family of devices in similar ? 140mA (Typical) Current Sink per Channel at packages

The ULQ2001, ULQ2003 and ULQ2004 are high voltage, high current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. The versions interface to all common logic families
