The ULN2003V12DR is a Low-power 7-channel Relay Driver features 7 low output impedance drivers that minimize on-chip power dissipation. When driving a typical 12V relay coil a ULN2003V12 will dissipate up to 12 times lower power than an equivalent ULN2003A. The ULN2003V12 supports 3.3 to 5V CMOS logic input interface thus making it compatible to a wide range of micro-controllers and other logic interfaces. It 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. This relay driver provides flexibility of increasing current sink capability through combining several adjacent channels in parallel.
