ULN200xA/ULQ200xA Darlington Transistor Arrays

Texas Instruments ULN200xA/ULQ200xA High-Voltage High-Current Darlington Transistor Arrays consist of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500mA. The Darlington pairs can be paralleled for higher current capability. The TI ULN200xA/ULQ200xA transistor array has a 2.7kΩ series base resistor for each Darlington pair for operation directly with TTL or 5V CMOS devices. The Texas Instruments ULN200xA/ULQ200xA is designed for a variety of applications, including relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
