Terms of use

A searchable catalogue of programmable logic part numbers, and a way to ask about availability and pricing. The catalogue is reference information compiled from manufacturer documentation and other sources. Listing a part is not an offer to sell it, a statement that it is in stock, or a guarantee that it can be obtained.

We compile specifications from manufacturers' own documentation and record where each figure came from. We take that seriously and correct errors promptly when they are reported. Even so, catalogue data is provided for reference and may be incomplete or out of date.

Always verify against the manufacturer's datasheet before ordering, designing in, or committing to a build. Where we link a datasheet, the manufacturer's document is authoritative and ours is not.

• Sending an enquiry costs nothing and commits you to nothing. It is a request for us and our partners to look, not an order.
• Any quotation is an invitation to deal, not a binding offer. Pricing, availability and lead times in the market for these parts move quickly, and a quotation is valid only for the period it states.
• A contract is formed only when an order is expressly accepted in writing — by us or by the supplying partner, whoever is selling to you.
• Where a partner supplies you directly, your contract is with that partner and on their terms. We will always tell you who you are dealing with.

Filling a requirement — particularly for obsolete or allocated parts — means going out to suppliers. We work with a network of them, and we choose who we work with carefully.

We are not responsible for the acts, omissions, goods or services of any third-party supplier. Goods supplied by a partner carry that partner's warranty, inspection, testing and returns terms, not ours. Where counterfeit-avoidance, testing or specific date codes matter to you, say so in your enquiry and we will make it a condition of sourcing — but the supplying party remains responsible for meeting it.

• We don't publish stock figures or prices. There is no live inventory behind this site and we will not invent one. Availability is checked on request, against the market on the day.
• We don't claim to be an authorised distributor. We are independent and not affiliated with, appointed by, or endorsed by any manufacturer. Manufacturer names, part numbers and logos are their property and are used only to identify the devices catalogued here.
• We don't claim parts are equivalent. A different speed grade, package or temperature range is a different part. Related parts are described by how they actually differ, and substitution is your engineering decision.

Use it for genuine sourcing and research. Please don't scrape it wholesale, resell the catalogue, submit false enquiries, or try to interfere with the service. The catalogue's selection, arrangement and compiled data are ours; the underlying part numbers and manufacturer trademarks belong to their owners.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited.

Subject to that, we are not liable for indirect or consequential loss, loss of profit, production, contracts or goodwill, and our total liability in connection with the site or any sourcing enquiry is limited to the amount you have paid us, if any, in respect of the matter concerned. This site is provided as-is and we do not warrant that it will be uninterrupted or error-free.

Semiconductors are subject to export controls. Where we publish an ECCN or HTS code we reproduce it from the manufacturer's own classification, and it is your responsibility to confirm the correct classification and to comply with the export, re-export and sanctions rules that apply to your shipment and end use.

We may update these terms; the date at the top shows when they last changed materially. Questions about anything here, or about a specific enquiry, go to [email protected].

How we handle your information is set out in our privacy notice.
