3 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

Ω series base resistor

for each Darlington pair for operation directly with

TTL or 5-V CMOS devices.

The ULx2004A devices have a 10.5-k

Ω series base

resistor to allow operation directly from CMOS

devices that use supply voltages of 6 V to 15 V. The

required input current of the ULx2004A device is

below that of the ULx2003A devices, and the required

voltage is less than that required by the ULN2002A

device.
