The ULN2003V12 is a low power upgrade of TI’s popular ULN2003 family of 7-channel
Darlington transistor array. The ULN2003V12 sink 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...
