I2C / SPI Interface ICs
I2C and SPI interface ICs extend and protect the short-reach buses that tie processors to sensors and peripherals, including GPIO expanders, bus buffers, multiplexers, and bridges. Engineers compare bus speed, address options, channel count, supply voltage, and hot-swap or isolation support. Compare I2C and SPI interface prices, stock, and lifecycle status across distributors on Circuit Center.
Manufacturers listed in I2C / SPI Interface ICs on Circuit Center include NXP Semiconductors, Microchip, Microchip Technology, Texas Instruments, Analog Devices, Maxim/ADI, Infineon Technologies and Semtech.
