The ULN2003LV is a low-voltage and low power upgrade of TI’s popular ULN2003 family of 7-channel Darlington transistor array. The ULN2003LV sink driver features 7 low output impedance drivers to support low voltage relay and inductive coil applications. The low impedance drivers minimize on-chip power dissipation; up to 5 times lower for typical 3V relays. The ULN2003LV driver is pin-to-pin compatible with ULN2003 family of devices in similar packages.

The ULN2003LV supports 3.3V to 5V CMOS logic input interface thus making it compatible to a wide range of micro-controllers and other logic interfaces. The ULN2003LV features an improved input interface that minimizes the input DC current drawn from the external drivers. The ULN2003LV features an input RC snubber that greatly improves its performance in noisy operating conditions. The ULN2003LV channel inputs feature an internal input pull-down resistor thus allowing input logic to be tri-stated. The ULN2003LV may also support other logic input levels, for example, TTL and 1.8V, refer to the Application Information section for details.

The ULN2003LV provides flexibility of increasing current sink capability through combining several adjacent channels in parallel. Under typical conditions the ULN2003LV can support up to 1.0A of load current when all 7-channels are connected in parallel. The ULN2003LV can also be used in a variety of applications requiring a sink drivers like driving LEDs and Logic Level Shifting.
