PI4MSD5V9545B/45C ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 4 Channel I2C bus Switch with Interrupt Logic and Reset Features  1-of-4 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, Description The PI4MSD5V9545B is a quad 1-of-4 bidirectional translating switch, controlled via the I2C bus. The SCL/SDA upstream pair fans out to four SCx/SDx downstream pairs, or channels. 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- Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. Four interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output, INT, acts as an AND of the four interrupt inputs. An active LOW reset input allows the PI4MSD5V9545B to recover f...
