2V, Description The PI4MSD5V9542A 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.

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- Only one SCx/SDx channel is selected at a time, determined by the contents of the programmable control register.
Two interrupt inputs, INT0 and INT1, one for each of the SCx/SDx downstream pairs, are provided.
One interrupt output, INT, which acts as an AND of the two interrupt inputs, is provided.
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 VCC pin can be used to limit the maximum A114, and 1000 V CDM per JESD22-C101  Latch-up testing is done to JEDEC Standard high voltage which will be passed by the PI4MSD5V9542A.
This allows the use of different bus JESD78 which exceeds 100 mA  Packages offered: SOIC-14W,TSSOP-14L voltages on each SCx/SDx pair, so that1.
