The ULN2003A/L and ULN2004A/L are the standard Darlington Note that the ULN20xxA series (dual in-line 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 package) and ULN20xxL series (small-outline load current capability. The ULN2023A/L and ULN2024A/L will IC package) are electrically identical and share withstand 95 V in the OFF state. a common terminal number assignment. These Darlington arrays are furnished in 16-pin dual in-line plastic packages (suffix “A”) and 16-lead surface-mountable SOICs (suffix “L”). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. All devices are rated for operation over the temperature range of -20°C to +85°C. Most (see matrix, next page) are also available for operation to -40°C; to order, change the prefix from “ULN” to “ULQ”.
