产品概述
The PCA9617ADPJ is a level translating Fm+ CMOS I2C-bus Repeater provides level shifting between low voltage and higher voltage fast-mode Plus (Fm+) I2C-bus or SMBus applICations. While retaining all the operating modes and features of the I2C-bus system during the level shifts, it also permits extension of the I2C-bus by providing bi-directional buffering for both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 540pF at 1MHz or up to 4000pF at lower speeds. Using the PCA9617A enables the system designer to isolate two halves of a bus for both voltage and capacitance. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the PCA9617A is unpowered.
