The PCA9509DP,118 is a robust level translating I²C-bus repeater from NXP Semiconductors, designed to provide bidirectional voltage-level translation in multi-voltage systems. This device is particularly useful for applications where an I²C-bus needs to communicate between different voltage nodes within a system, ensuring seamless communication between devices operating at different voltages.

Key Features

• Voltage Level Translation: The PCA9509DP,118 is capable of translating between voltages as low as 0.9V and up to 5.5V on the I²C-bus, making it versatile for a wide range of applications.
• I²C-bus Repeater: It functions as a repeater for the I²C-bus, allowing for extension of the I²C-bus by buffering both the data (SDA) and the clock (SCL) lines, thus enabling longer bus lengths and more connected devices.
• Hot-Swappable: This device supports hot-swapping, a feature that allows devices to be inserted or removed from a system without needing to power down the system.
• Low Standby Current: It has a low standby current which makes it suitable for power-sensitive applications.
• No Direction Pin: The PCA9509DP,118 does not require a direction control pin, simplifying the design for applications that need bidirectional voltage-level translation.

Applications

The PCA9509DP,118 is ideal for a variety of applications, including but not limited to:

• Mobile Devices
• Consumer Electronics
• Industrial Control
• Automotive Modules
• Power Management Modules

Product Specifications

The PCA9509DP,118 is provided in a TSSOP8 package, which is a thin-shrink small outline package with 8 pins. This package is widely used in the industry due to its small footprint and ease of integration into a variety of circuit designs. The product is also compliant with the I²C-bus Fast-mode Plus (Fm+) specification, supporting higher data transfer speeds up to 1 Mbit/s.
