Overview
PCA9617A Level translating Fm+ I2C-bus repeater Rev.
1 — 20 March 2013 Product data sheet 1.
General description The PCA9617A is a CMOS integrated circuit that provides level shifting between low voltage (0.
8 V to 5.
5 V) and higher voltage (2.
2 V to 5.
5 V) 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 bidirectional buffering for both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 540 pF at 1 MHz or up to 4000 pF at lower speeds.
Using the PCA9617A enables the system designer to isolate two halves of a bus for bo...
