These are genuine SGS Thompson (ST) ULN 2003A parts.
A high voltage, high current Darlington array each containing seven open collector Darlington pairs with common emitters. Each channel rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.
• Seven Darlingtons per package
• Output current 500 mA per driver (600 mA peak)
• Output voltage 50 V
• Integrated suppression diodes for inductive loads
• Outputs can be paralleled for higher current
• TTL/CMOS/PMOS/DTL compatible inputs
• Inputs pinned opposite outputs to simplify layout
These genuine ST parts are date coded W994K0044 they came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. Ideal if repairing or refurbishing an older piece of equipment and wishing to add authenticity.
Having been in storage for some time we have classified them as ‘new other’. In fact they are still in their original tubes and ‘as new’ in all respects.

We Purchase Surplus Stock!!!If you or your company has items similar to the above, or indeed any electronic components surplus to requirements, please contact us with details as we are keen to increase our stock profile.
As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
