2 Channel I2C bus switch with interrupt logic and Reset
Features
1-of-2 bidirectional translating multiplexer
I2C-bus interface logic
Operating power supply voltage:1.65 V to 5.5 V
Allows voltage level translation between 1.2V,
1.8V,2.5 V, 3.3 V and 5 V buses
Low standby current
Low Ron switches
Channel selection via I2C bus
Power-up with all multiplexer channels deselected
Capacitance isolation when channel disabled
No glitch on power-up
Supports hot insertion
5 V tolerant inputs
0 Hz to 400 kHz clock frequency
ESD protection exceeds 8000 V HBM per JESD22-
A114, and 1000 V CDM per JESD22-C101
Latch-up testing is done to JEDEC Standard
JESD78 which exceeds 100 mA
Packages offered: SOIC-14W,TSSOP-14L
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
PI4MSD5V9543B to recover from a situation where one
of the downstream 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 VCC pin can be used to limit the maximum high
voltage which will be passed by the PI4MSD5V9543X.
This allows the use of different bus voltages on each
SCx/SDx pair, so that 1.2V,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 PI4MSD5V9543A and PI4MSD5V9543B are
identical except for the fixed portion of the slave address.

Description
The PI4MSD5V9543B 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
