Data Sheet
29304.3E
Featuring continuous load current ratings to 500 mA for each of
the drivers, the Series ULN28xxA/LW and ULQ28xxA/LW highvoltage,
high-current Darlington arrays are ideally suited for interfacing
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 ty cycle depending on ambient
temperature and number of drivers turned on simultaneously. 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 ULx2803A, ULx2803LW, ULx2823A, and ULN2823LW
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 ULx2804A, ULx2804LW, ULx2824A, and ULN2824LW
have series input resistors for operation directly from 6 V to 15 V
CMOS or PMOS logic outputs.
The ULx2803A/LW and ULx2804A/LW 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 ULx2823A/LW and ULx2824A/
LW will withstand 95 V in the off state.
These Darlington arrays are furnished in 18-pin al in-line
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.
