PCA9543A/43B/43C
2-channel I
2
C-bus switch with interrupt logic and reset
Rev. 05 — 17 November 2008
Product data sheet
1. General description
The PCA9543A/43B/43C is a bidirectional translating switch, controlled by the I
2
C-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 I
2
C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets the
I
2
C-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
DD
pin 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.
