PCA9548A Low Voltage 8-Channel I2C Switch with Reset

The PCA9548A is a versatile 8-channel I2C switch that enables bidirectional communication between multiple I2C buses. It resolves I2C slave address conflicts by providing separate downstream channels controlled via a programmable register. Supporting voltage-level translation, it ensures compatibility between different bus voltage levels, making it ideal for applications requiring flexible, reliable I2C communication.

Features:
Bidirectional Translating Switches: 1-of-8 configuration.
I2C/SMBus Compatibility: Seamless integration with standard protocols.
Reset Functionality: Active-low reset to recover from errors.
Hot Insertion: Supports adding devices without powering down.
Voltage-Level Translation: Works across 1.8 V, 2.5 V, 3.3 V, and 5 V buses.
Power-Up Behavior: Channels deselected by default for safety.
Low On-Resistance (RON): Ensures minimal signal degradation.
Standby Current: Low power consumption during idle state.
Expandable Addressing: Three hardware address pins allow up to eight PCA9548A devices on the same bus.
Applications:

Server and network equipment
Factory automation systems
Products with I2C slave address conflicts (e.g., multiple sensors)
Telecom switching equipment
