Description
The ULx200xA devices are high-voltage, high-current?Darlington transistor arrays. Each consists of seven?NPN Darlington pairs that feature high-voltage?outputs with common-cathode clamp diodes for
switching inductive loads.
The collector-current rating of a single Darlington pair?is 500 mA. The Darlington pairs can be paralleled for?higher current capability. Applications include relay?drivers, hammer drivers, lamp drivers, display drivers
(LED and gas discharge), line drivers, and logic?buffers. For 100-V (otherwise interchangeable)?versions of the ULx2003A devices, see the SLRS023?data sheet for the SN75468 and SN75469 devices.
The ULN2002A device is designed specifically for use?with 14-V to 25-V PMOS devices. Each input of this?device has a Zener diode and resistor in series to?control the input current to a safe limit. The?ULx2003A devices have a 2.7-k? series base resistor?for each Darlington pair for operation directly with?TTL or 5-V CMOS devices.
