PCA9617A集成電路（IC）的信號緩沖器、中繼器、分離器規(guī)格書PDF中文資料

PCA9617A屬于集成電路（IC）的信號緩沖器、中繼器、分離器。由安森美半導體公司制造生產的PCA9617A信號緩沖器、中繼器、分離器信號緩沖器、中繼器和分離器系列中的產品適用于遠距離電氣互連或電纜系統(tǒng)的數(shù)字信息傳輸。所有實際互連系統(tǒng)都具有非理想特性，該系列產品主要用于解決數(shù)字信息傳輸過程中因此造成的模擬問題。此外，還有其他功能，例如不同物理接口樣式之間的轉換和多路復用。

Level-Translating Fm+ I2C-Bus Repeater

The PCA9617A is an I2C?bus repeater that provides level shifting between low voltage (0.8 V to 5.5 V) and higher voltage (2.2 V to 5.5 V) for Fast?Mode Plus (Fm+) I2C?bus or SMBus applications.

Features

? Two 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
