Two-Channel I2C-Bus Multiplexer

PCA9540B Active

The PCA9540B is a 1-of-2 bidirectional translating multiplexer, controlled via the I²C-bus. The SCL/SDA upstream pair fans out to two SCx/SDx downstream pairs, or channels. Only one SCx/SDx channel is selected at a time, determined by the contents of the programmable control register.

A power-on reset function puts the registers in their default state and initializes the I²C-bus state machine with no channels selected.

The pass gates of the multiplexer are constructed such that the VDD pin can be used to limit the maximum high voltage that is passed by the PCA9540B. This allows the use of different bus voltages on each SCx/SDx pair, so that 1.8 V, 2.5 V or 3.3 V parts can communicate with 5 V parts without any additional protection. External pull-up resistors can pull the bus up to the desired voltage level for this channel. All I/O pins are 5 V tolerant.

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode. 1442125286808710770774 PSP 751.0 KB None None documents None 1442125286808710770774 /docs/en/user-guide/UM10204.pdf 750958 /docs/en/user-guide/UM10204.pdf UM10204 documents N N 2016-07-12 I2C-bus specification and user manual /docs/en/user-guide/UM10204.pdf /docs/en/user-guide/UM10204.pdf User Guide N 132339537837198660 2024-10-24 pdf N en Oct 1, 2021 132339537837198660 User Guide Y N I2C-bus specification and user manual 6 1.0 English 1442125429801702674389 PSP 749.6 KB Registration without Disclaimer None documents Extended 1442125429801702674389 /secured/assets/documents/en/user-guide/UM10528.pdf 749626 /secured/assets/documents/en/user-guide/UM10528.pdf UM10528 documents Y N 2012-02-06 PCA9632 demonstration board OM13269 /webapp/Download?colCode=UM10528 /secured/assets/documents/en/user-guide/UM10528.pdf User Guide N 132339537837198660 2025-02-10 pdf Y en Feb 6, 2012 132339537837198660 User Guide Y N PCA9632 demonstration board OM13269 Brochure Brochure 1 7 1.0 English 1442124653171725284460 PSP 656.7 KB None None documents None 1442124653171725284460 /docs/en/brochure/75016529.pdf 656663 /docs/en/brochure/75016529.pdf 75016529 documents N N 2011-09-12 Add design fl exibility with multi-channel I2C/SMBus muxes and switches;

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode.
