Devices in this family are used in conjunction with microcontrollers, microprocessors, or similar devices for the purpose of increasing the number of signal connections available for connecting peripheral devices. The typical concept of operation involves the use of serial communications requiring only a few I/O lines on the host device to read/write the status of many input/output pins on the expander device. The technique exchanges speed of communication for increased connectivity, and is best suited for applications where fast response is not critical, such as in many human interface applications.
FAQ
Which parts are supplied in stock?
Shenzhen Cluster Technology Co. supplies integrated circuits (ICs), resistors, capacitors, inductors and diodes from stock. Open a part number to see the brand and specifications, then request a quote for quantity and lead time. Genuine stock is confirmed when you inquire.
How do I request a quote by part number?
Open the part page and check the brand, package and electrical specifications against your requirement, then send an inquiry with the part number, quantity and target lead time. For several lines, use BOM matching and list every part once.
Do you support BOM matching?
Yes. Send the part numbers, quantities and brands. We check integrated circuits, resistors, capacitors and inductors against current stock, then reply with the quantity that can be delivered and the lines that need to be ordered.
