Overview
2003 THRU 2024 HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 Ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads, the Series ULN20xxA/L high-voltage, high-current Darlington arrays feature continuous load current ratings to 500 mA for each of the seven drivers.
At an appropriate duty cycle depending on ambient temperature and number of drivers turned ON simultaneously, 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 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.
No.
A-9594 Note that the ULN20xxA series (dual in-line package) and ULN20xxL series (small-outline IC package) are electrically identical and share a common terminal number assignment.
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.
The ULN2023A/L and ULN2024A/L will withstand 95 V in the OFF state.
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; t...
