The ULN2003LVDR is a relay and inductive load Sink Driver features 7 low output impedance driver 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. It supports 3.3 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. It provides flexibility of increasing current sink capability through combining several adjacent channels in parallel. Under typical conditions the ULN2003LV can support up to 1A of load current when all 7-channel is connected in parallel.
