世界上最快的I2C总线的GPIO NXP Fast-mode Plus (Fm+) GPIO family PCA967x World’s fastest GPIO for I2C-bus Designed for the Fast-mode Plus version of the I2C-bus, these GPIO provide faster control of slave devices and enable a higher drive capability. They’re backward compatible with the Fast-mode and standard I2C-bus protocols, and are ideal for use as LED controllers and switch-input monitors. Key features 4Wide range of package types: SO, They improve on previous generations 4 8- and 16-bit I/O ports that default to TSSOP, SSOP, QSOP, DHVQFN, of I2C-bus GPIO by supporting higher inputs on power-up ……
