PCA9617A - NXP Semiconductors

PCA9617A Level translating Fm I2C-bus repeater

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 bidirectio.

Features

 2 channel, bidirectional buffer isolates capacitance and allows 540 pF on either side of the device at 1 MHz and up to 4000 pF at lower speeds
 Voltage level translation from 0.8 V to 5.5 V and from 2.2 V to 5.5 V
 Footprint and functional replacement for PCA9517A at Fast-mode speeds
 Port A operating supply voltage range of 0.8 V to 5.5 V with normal levels Free Datasheet http://www.datasheet4u.com/ NXP Semiconductors PCA9617A Level translating Fm+ I2C-bus repeater
 Port B operating supply voltage range of 2.2 V to 5.5 V with static offset level
 5 V tolerant I2C-bus and enable pin.
