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.
