The is a low-voltage and low power upgrade of TI's popular ULN2003 family of 7-channel Darlington transistor array. The ULN2003LV sink driver features 7 low output impedance drivers to support low voltage relay and inductive coil applications. The low impedance drivers minimize onchip power dissipation; to 5 times lower for typical 3V relays. The ULN2003LV driver is pin-to-pin compatible with ULN2003 family of devices in similar packages. The ULN2003LV supports to 5V CMOS logic input interface thus making it compatible to a wide range of micro-controllers and other logic interfaces. The ULN2003LV features an improved input interface that minimizes the input DC current drawn from the external drivers. The ULN2003LV features an input RC snubber that greatly improves its performance in noisy operating conditions. The ULN2003LV channel inputs feature an internal input pull-down resistor thus allowing input logic to be tri-stated. The ULN2003LV may also support other logic input levels, e.g. TTL and 1.8V, refer to the Application Information section for details. As shown in Table 1, each output of the ULN2003LV features an internal free-wheeling diode connected in a common-cathode configuration at the COM pin. The ULN2003LV provides flexibility of increasing current sink capability through combining several adjacent channels in parallel. Under typical conditions the ULN2003LV can support 1.0A of load current when all 7-channels are connected in parallel. The ULN2003LV can also be used in a variety of other applications requiring a sink drivers. The ULN2003LV is available in 16-pin SOIC and 16-pin TSSOP packages. Table 1. ULN2003LV Function Table(1)

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.


Maximum dissipation values for retaining device junction temperature of 150°C Refer to TI's design support web page at www.ti.com/thermal for improving device thermal performance Operating at the absolute TJ-max of 150°C can affect reliability­ for higher reliability it is recommended to ensure < 125°C

The typical continuous current rating is limited by VOL= 0.4V. Whereas, absolute maximum operating continuous current may be limited by the Thermal Performance.parameters listed in the Dissipation Rating Table and other Reliability parameters listed in the Recommended Operating ConditionsTable. Refer to the Absolute Maximum Ratings Table for TJ dependent absolute maximum GND-pin current. Rise and Fall propagation delays, tPHL and tPLH, are measured between 50% values of the input and the corresponding output signal amplitude transition. Guaranteed by design only.
