This is the datasheet link the distributor returned with the part record. We pass it through as they gave it, and we have not opened it - there are more than 300,000 of these and we verify only the ones we curate by hand. If it does not resolve, that is the distributor’s record, not the part.

Common questions about M74HC688RM13TR

7 questions▾
Is M74HC688RM13TR in stock?
Not currently. DigiKey quotes M74HC688RM13TR but hold no stock, so it ships on factory lead time. Confirm the lead time with the distributor before you commit.
How much does M74HC688RM13TR cost?
RM 0.8620 is the lowest unit price on this page, from DigiKey. Prices fall as quantity rises; the full price break ladder is in the quotes table. Figures come from the distributor API and are indicative, not a binding quote.
Who supplies M74HC688RM13TR?
DigiKey. It is authorized, franchised distributor quoting through its own API. TracedParts carries no broker or open-market listings.
How old are these prices?
The catalogue is re-pulled from the distributors' APIs once a day, and the line under the Quotes heading says which pull the figures on this page came from. Prices and stock can move between pulls, so treat them as indicative and confirm on the distributor's site before you order.
Who quoted these prices?
Every row on the site comes from an authorized, franchised distributor through its own API: DigiKey, Mouser or element14. There are no broker or open-market listings on TracedParts. If a source ever changes, the row will say so.
Why do you show the source before the price?
Because who sold it decides what happens at incoming inspection, and a table sorted by price alone hides that. Rows are grouped by the distributor's status first and ordered by unit price inside the group.
Why are prices in ringgit?
Distributors quote in US dollars. TracedParts converts to MYR at a fixed reference rate that is printed on the page, not a live FX feed, so the ringgit figure is a sourcing estimate rather than the amount you will be billed.
