Note that the ULx28xxA series (dual in-line

package) and ULx28xxLW series (small-

outline IC package) are electrically identical

and share a common terminal number assign-

the drivers, the Series ULN28xxA/LW and ULQ28xxA/LW high-

voltage, high-current Darlington arrays are ideally suited for interfac-

ing between low-level logic circuitry and multiple peripheral power

loads. Typical power loads totaling over 260 W (350 mA x 8, 95 V)

can be controlled at an appropriate duty cycle depending on ambient

temperature and number of drivers turned on simultaneously. Typical

loads include relays, solenoids, stepping motors, magnetic print ham-

mers, multiplexed LED and incandescent displays, and heaters. All

devices feature open-collector outputs with integral clamp diodes.

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.

have series input resistors for operation directly from 6 V to 15 V

CMOS or PMOS logic outputs.

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 ULx2823A/LW and ULx2824A/

LW will withstand 95 V in the off state.

plastic packages (suffix ‘A’) or 18-lead small-outline plastic packages

(suffix ‘LW’). All devices are pinned with outputs opposite inputs to

facilitate ease of circuit board layout. Prefix ‘ULN’ devices are rated

for operation over the temperature range of -20°C to +85°C; prefix

‘ULQ’ devices are rated for operation to -40°C.
