恩智浦PCA967x系列的高速模式Plus（FM +）GPIO

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
