TCA9509 Product details

Description

This TCA9509 integrated circuit is an I2C bus/SMBus Repeater for use in I2C/SMBus systems.

It can also provide bidirectional voltage-level translation (uptranslation/down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-mode applications.

Features

1 Two-Channel Bidirectional Buffer.
I2C Bus and SMBus Compatible.
Operating Supply Voltage Range of 2.7 V to 5.5 V on B side.
Operating Voltage Range of 0.9 V to 5.5 V on A-Side.
Voltage-Level Translation From 0.9 V to 5.5 V and 2.7 V to 5.5 V.
Active-High Repeater-Enable Input.
Requires No External Pullup Resistors on Lower-Voltage Port-A.
Open-Drain I2C I/O.
5.5-V Tolerant I2C and Enable Input Support Mixed-Mode S.
