The ULN2003V12 and ULN2003F12 are multi-channel sink drivers comprised of 7-channel and 4-channel output stages respectively. The ULN2003V12 sink driver features 7 low output impedance drivers that minimize on-chip power dissipation and an actual low power upgrade version for popular ULN2003A family in real applications. When driving a typical 12V relay coil, a ULN2003V12 will dissipate 12 times lower power compared to ULN2003A. ULN2003F12 is a lower power variant benefiting from fewer channel integration and a better fit for applications requiring only 4-channel drivers, such as driving low voltage stepping motors, etc.?The ULN2003V12 and ULN2003F12 both support 3.3V to 5V CMOS logic input interface, thus making it compatible to a wide range of micro-controllers and other logic interfaces, and also feature an improved input interface that minimizes the input DC current drawn from the external drivers. The input RC snubber circuit integrated at ULN2003V12 and ULN2003F12 improves the performance in noisy operating conditions, and the internal pull-down resistor at input stage helps allow input logic to be tri-stated.?As shown in the Functional Diagram, each output of the ULN2003V12 and ULN2003F12 features an internal free-wheeling diode connected in a common-cathode configuration at the COM pin which provides flexibility of increasing current sink capability through combining several adjacent channels in parallel. Under typical conditions the ULN2003V12 can support up to 1.0A of load current when all 7-channels are connected in parallel.
