DESCRIPTION
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 than an equivalent
ULN2003A. The ULN2003V12 driver is pin-to-pin
compatible with ULN2003 family of devices in similar
packages.
The ULN2003V12 supports 3.3V 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. The ULN2003V12 also supports other logic
input levels, e.g. TTL and 1.8V; see typical
characteristics section for details.
As shown in the , each output of the ULN2003V12
features an internal free-wheeling diode connected in
a common-cathode configuration at the COM pin.
The ULN2003V12 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.
The ULN2003V12 can also be used in a variety of
other applications requiring a sink drivers. The
ULN2003V12 is available in 16-pin SOIC and 16-pin
TSSOP packages.
