ULN2003V12 SLRS060A – MAY 2012 – REVISED JUNE 2012 www.ti.com 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.

ULN2003V12 www.ti.com SLRS060A – MAY 2012 – REVISED JUNE 2012 APPLICATION INFORMATION TTL and other Logic Inputs ULN2003V12 input interface is specified for standard 3V and 5V CMOS logic interface. However, ULN2003V12 input interface may support other logic input levels as well. Refer to Figure 10 and Figure 11 to establish VOL and the corresponding typical load current levels for various input voltage ranges. Application Information section shows an implementation to drive 1.8V relays using ULN2003V12.

The ULN2003V12’s each channel input and output logic levels can also be set independently. When using different channel input and output logic voltages connect the ULN2003V12 COM pin to the maximum voltage. VSUP Level Shift Supply(Up to 20V) Logic Inputs (1.

This setup configures ULN2003V12’s channel clamp diodes OUT5 – OUT7 in a diode-OR configuration and thus the maximum supply among VSUP1, VSUP2 and VSUP3 becomes available at the COM pin. The maximum supply is then used as a pull-up voltage for level shifters.

The current flowing through the resistor R1 is copied on all other channels. To increase the current sourcing connect several output channels in parallel. To ensure best current copying set voltage drop across connected load such that VOUTx matches to VOUT7. VSUP VIN (Up to 5.

The unconnected input channels can be used for other functions. When an input pin is left open the internal 300kΩ pull down resistor pulls the respective input pin to GND potential. For higher noise immunity use an external short across an unconnected input and GND pins.
