ULN2003V12, ULN2003F12
Multi-Channel Relay and Inductive Load Sink Driver
Description
Pin Assignments
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.

IN1 1
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 7channels are connected in parallel.

4. Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
5. All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted.
6. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is
PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of +150°C can affect reliability.
7. Maximum power dissipation is a function of TJ(max), θJC, and TA. The maximum allowable power dissipation at any allowable ambient temperature is
PD = (TJ(max) – TC)/θJA. Operating at the absolute maximum TJ of +150°C can affect reliability.
