2003 THRU2024HIGH-VOLTAGE, HIGH-CURRENTDARLINGTON ARRAYS12345678161514131211109Ideally suited for interfacing between low-level logic circuitry andmultiple peripheral power loads, the Series ULN20xxA/L high-voltage,high-current Darlington arrays feature continuous load current ratingsto 500 mA for each of the seven drivers. At an appropriate duty cycledepending on ambient temperature and number of drivers turned ONsimultaneously, typical power loads totaling over 230 W (350 mA x 7,95 V) can be controlled. Typical loads include relays, solenoids,stepping motors, magnetic print hammers, multiplexed LED andincandescent displays, and heaters. All devices feature open-collectoroutputs with integral clamp diodes.The ULN2003A/L and ULN2023A/L have series input resistorsselected for operation directly with 5 V TTL or CMOS. These deviceswill handle numerous interface needs — particularly those beyond thecapabilities of standard logic buffers.The ULN2004A/L and ULN2024A/L have series input resistors foroperation directly from 6 to 15 V CMOS or PMOS logic outputs.Data Sheet29304FDwg. No. A-9594Note that the ULN20xxA series (dual in-linepackage) and ULN20xxL series (small-outlineIC package) are electrically identical and sharea common terminal number assignment.The ULN2003A/L and ULN2004A/L are the standard Darlingtonarrays. The outputs are capable of sinking 500 mA and will withstandat least 50 V in the OFF state. Outputs may be paralleled for higherload current capability. The ULN2023A/L and ULN2024A/L willwithstand 95 V in the OFF state.These Darlington arrays are furnished in 16-pin dual in-line plasticpackages (suffix “A”) and 16-lead surface-mountable SOICs (suffix“L”). All devices are pinned with outputs opposite inputs to facilitateease of circuit board layout. All devices are rated for operation over thetemperature range of -20°C to +85°C. Most (see matrix, next page) arealso available for operation to -40°C; to order, change the prefix from“ULN” to “ULQ”.ABSOLUTE MAXIMUM RATINGSOutput Voltage, VCE(ULN200xA and ULN200xL)........ 50 V(ULN202xA and ULN202xL)........ 95 VInput Voltage, VIN................................ 30 VContinuous Output Current,IC................................................. 500 mAContinuous Input Current, IIN........... 25 mAPower Dissipation, PD(one Darlington pair)..................... 1.0 W(total package).......................
