ULN2003AN General Description

The ULN2003AN is a versatile high-voltage, high-current Darlington transistor array featuring seven NPN Darlington pairs with common-cathode clamp diodes. Each Darlington pair has a collector-current rating of 500 mA, which can be paralleled for increased current capability. This device is ideal for a variety of applications such as relay drivers, lamp drivers, and logic buffers. For PMOS devices with supply voltages between 14 V to 25 V, the ULN2002A is specifically designed with Zener diodes and resistors to control input current. The ULx2003A devices are equipped with a 2.7 kΩ base resistor for direct operation with TTL or 5 V CMOS devices, while the ULx2004A devices feature a 10.5 kΩ base resistor for compatibility with CMOS devices operating at 6 V to 15 V. The ULx2004A device has lower input current and voltage requirements compared to the ULx2003A and ULN2002A devices, making it a convenient choice for various electronic applications
