Description

The PCA9546ARGVR is a 4-channel I2C bus multiplexer designed to allow multiple I2C devices to communicate with a master device. It enables the selection of one of four I2C channels, facilitating connection to multiple I2C devices while avoiding address conflicts. The PCA9546A operates with a supply voltage range of 2.3V to 5.5V and supports standard-mode (up to 100 kHz) and fast-mode (up to 400 kHz) I2C communication.
Key features include:
- Four independent I2C buses that can be individually selected.
- A single interrupt output that indicates active channels.
- Low power consumption and compatibility with various I2C bus speeds.
The device is often used in applications where multiple I2C sensors, displays, or other peripherals are needed, enabling efficient communication without requiring additional address space. It is available in various packages, making it suitable for a range of design requirements.

Features

The PCA9546ARGVR is a 6-channel I2C multiplexer that allows multiple I2C buses to share the same master bus while preventing conflicts. Key features include:
1. Channel Selection: It has six selectable channels (A0 to A5) that can connect to multiple I2C devices on a single master bus.
2. I2C Compatibility: Supports standard I2C protocol with a 2-wire interface, allowing easy integration with I2C-compatible devices.
3. Wide Operating Voltage: Operates between 2.3V and 5.5V, making it suitable for various supply voltages.
4. Low Power Consumption: Designed for low power operation, making it ideal for battery-powered applications.
5. Fast Data Rates: Supports data rates up to 1 Mbps, ensuring efficient communication.
6. Interrupt Feature: Provides an interrupt output to signal the master when a channel is selected.
7. Compact Package: Available in a small TSSOP-20 package, optimizing space in PCB design.
Overall, the PCA9546ARGVR is an efficient solution for expanding I2C bus capabilities in complex systems.

Package

The PCA9546ARGVR is packaged in a VQFN (Very Thin Quad Flat No-lead) format, specifically a 16-pin version. This package type provides a compact footprint and is suitable for surface mount applications.

Pinout

The PCA9546ARGVR is a 6-channel I2C bus switch with a total of 16 pins. The pin count includes:
- 1 Ground (GND): Common ground reference.
- 1 VCC: Power supply input.
- 6 A pins (A0 to A5): These are the master I2C bus lines connecting to the master device.
- 6 B pins (B0 to B5): These are the slave I2C bus lines connecting to the slave devices.
- 1 Enable pin (EN): Activates the switching function of the device.
Function: The PCA9546A allows the user to control multiple I2C devices on the same bus without address conflicts. It enables communication with one of the selected slave devices while isolating the others, effectively managing bus traffic and facilitating the extension of I2C communication over longer distances or to multiple devices.
