0755-82798135I/O Expanders
I/O Expanders are interface ICs used to increase the number of input and output ports available to microcontrollers, processors and embedded systems. They are widely used in industrial control, communication equipment, consumer electronics, automotive electronics, medical devices, IoT products, smart home devices and embedded control applications.
This category includes GPIO expanders, I2C I/O expanders, SPI I/O expanders, port expanders, keypad interface expanders, LED control expanders and related interface control components. These devices are commonly selected based on interface type, number of I/O channels, supply voltage, interrupt support, output drive capability, package type and system compatibility.
TomatoElec supplies original I/O Expanders from recognized semiconductor manufacturers such as Texas Instruments, NXP, Microchip, STMicroelectronics, onsemi, Diodes Incorporated, Renesas, Infineon and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
