ULN2003L Overview
Key Features
- continuous load current ratings to 500 mA for each of the seven drivers
- Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters
- All devices feature open-collector outputs with integral clamp diodes
- The ULN2003A/L and ULN2023A/L have series input resistors selected for operation directly with 5 V TTL or CMOS
- These devices will handle numerous interface needs - particularly those beyond the capabilities of standard logic buffers
- The ULN2004A/L and ULN2024A/L have series input resistors for operation directly from 6 to 15 V CMOS or PMOS logic outputs
- Data Sheet 29304F Dwg
- The ULN2003A/L and ULN2004A/L are the standard Darlington arrays
- The outputs are capable of sinking 500 mA and will withstand at least 50 V in the OFF state
- Outputs may be paralleled for higher load current capability
