ULN2004A.

High-voltage, high-current darlington arrays each contains seven open collector darlington pairs with common emitters. Suitable for relay drivers, stepper and DC brushed motor drivers, lamp drivers, display drivers (LED and gas discharge), line drivers and logic buffers.

• Integrated suppression diode for inductive loads
• Output can be paralleled for higher current
• TTL/CMOS/PMOS/DTL compatible inputs
• Input pins are placed opposite to output pins to simplify layout
