Overview
The TCA9546APWR is a bidirectional translating switch manufactured by Texas Instruments, designed for I2C and SMBus applications. It features four independent switches that allow multiple I2C masters to communicate with multiple slave devices on the same bus without address conflicts. The device operates within a supply voltage range of 1.65 V to 5.5 V and supports data rates up to 400 kHz. It is housed in a 16-pin TSSOP package and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides four independent bidirectional translating switches for I2C and SMBus protocols
- Enables communication between multiple I2C masters and slaves on a single bus
- Supports low-voltage operation ranging from 1.65 V to 5.5 V
Applications
- I2C bus expansion in embedded systems
- SMBus interface management
- Multi-master I2C network configurations
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package and tape-and-reel packaging configuration. Confirm the component meets RoHS compliance standards as indicated by the manufacturer's documentation. Ensure the ordering part number matches the exact electrical specifications required for your design, particularly regarding the 1.65 V to 5.5 V operating range.
Selection Notes
Select this component when designing systems requiring isolation between multiple I2C or SMBus masters and slaves. It is suitable for applications needing bidirectional voltage translation within the specified range. Consider the TSSOP-16 package constraints for PCB layout. Verify compatibility with the target bus speed and voltage levels before integration.
Part Context
This component belongs to the TCA9546A series of bidirectional translating switches from Texas Instruments. It serves as a solution for managing complex I2C/SMBus topologies where address collisions might occur. The device facilitates seamless communication in multi-master environments by providing isolated switching paths for each channel.
Replacement Considerations
The PCA9546APWR is a pin-compatible alternative within the same family, offering similar functionality with potentially different voltage or performance characteristics. Verify datasheet details for both parts to ensure electrical compatibility before substitution.
