Ideally suited for interfacing between low-level logic circuitry and
multiple peripheral power loads, the Series LR2001A/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 120 W (350 mA x 7,
50 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 LR2001A/L have series input resistors selected for operation
directly with DTL TTL PMOS or CMOS. These devices will handle
numerous interface needs - particularly those beyond the capabilities of
standard logic buffers.
The LR2001A/L are the standard Darlington Array. The outputs
are capable of sinking 500 mA and will withstand at least 50V in the
OFF state.Outputs may be paralleled for higher load current capability.
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 -40
°C to +85°C.

Note that the LR2001A series (dual in-line
package) and LR2001L series (small-outline
IC package) are electrically identical and share
a common terminal number assignment.
