Description:

• The ULN2803A is an integrated circuit that has eight Darlington transistor arrays.
• It is commonly used to drive high-current loads using low-logic level digital circuits like TTL or CMOS.
• High Voltage, High Current Darlington Transistor Arrays: Each of the ULN2803A's eight Darlington couples can drive up to 500mA at 50V.
• Input Compatibility: Designed for direct interfacing with standard logic families like as TTL and CMOS.
• Integral Suppression Diodes: These include flyback diodes, which protect transistors from inductive loads.
