The ULN2003V12PWR is a relay and inductive load Sink Driver features 7 low output impedance drivers that minimize on-chip power dissipation. When driving a typical 12V relay coil an ULN2003V12 will dissipate up to 12 times lower power than an equivalent ULN2003A. 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 ULN2003V12 features an improved input interface that minimizes the input DC current drawn from the external drivers. The ULN2003V12 features an input RC snubber that greatly improves its performance in noisy operating conditions. The ULN2003V12 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 ULN2003V12 can support up to 1A of load current when all 7-channel is connected in parallel.
