HIGH-VOLTAGE, HIGH-CURRENT
DARLINGTON ARRAYS
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.
Dwg. No. A-9594
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.
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.
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”.
