1 pcs : PCA9646PW,118 - Digital Bus Switch ICs Buffered 4-Channel 2-Wire Bus Switch

PCA96xx 2-wire Bus Switch & Output Port NXP Semiconductors PCA96xx 2-wire Bus Switch & Output Port are monolithic CMOS integrated circuits for 2-wire bus interfaces, including I2C-bus, SMBus, PMBus, and other systems based on similar principles. The NXP Semiconductors PCA9646 Buffered 4-channel 2-wire Bus Switch has four outputs which may be independently enabled in any combination as determined by the contents of the programmable control register. Each I/O is impedance isolated from all others, thus allowing a total of five branches of 2-wire bus with the maximum specified load. The PCA9646 has excellent application to 2-wire bus address expansion and increasing of maximum load capacitance, such as in very large LED displays.
