PCA9543A/43B/43C

2-channel I²C-bus switch with interrupt logic and reset

Rev. 06 — 15 June 2009

Product data sheet

1. General description

The PCA9543A/43B/43C is a bidirectional translating switch, controlled by the I²C-bus.

The SCL/SDA upstream pair fans out to two downstream pairs, or channels. Any

individual SCx/SDx channels or combination of channels can be selected, determined by

the contents of the programmable control register. Two interrupt inputs, INT0 and INT1,

one for each of the downstream pairs, are provided. One interrupt output, INT, which acts

as an AND of the two interrupt inputs, is provided.

An active LOW reset input allows the PCA9543X to recover from a situation where one of

the downstream I²C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets the

I²C-bus state machine and causes all the channels to be deselected, as does the internal

power-on reset function.

The pass gates of the switches are constructed such that the V_DDpin can be used to limit

the maximum high voltage which will be passed by the PCA9543X. 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

pull the bus up to the desired voltage level for each channel. All I/O pins are 5 V tolerant.

The PCA9543A, PCA9543B and PCA9543C are identical except for the ﬁxed portion of

the slave address.
