PCA9542A  
2-channel I2C-bus multiplexer and interrupt logic  
Rev. 04 — 15 June 2009  
Product data sheet  
1. General description  
The PCA9542A 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.  
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 VDD pin can be used to  
limit the maximum high voltage which will be passed by the PCA9542A. 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.  
2. Features  
I 1-of-2 bidirectional translating multiplexer  
I I2C-bus interface logic; compatible with SMBus  
I 2 active LOW interrupt inputs (INT0, INT1)  
I Active LOW interrupt output (INT)  
I 3 address pins allowing up to 8 devices on the I2C-bus  
I Channel selection via I2C-bus  
I Powers up with all multiplexer channels deselected  
I Low Ron switches  
I Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses  
I No glitch on power-up  
I Supports hot insertion  
I Low standby current  
I Operating power supply voltage range of 2.3 V to 5.5 V  
I 5 V tolerant inputs  
I 0 Hz to 400 kHz clock frequency  
I ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per  
JESD22-A115 and 1000 V CDM per JESD22-C101  
I Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA  
I Packages offered: SO14, TSSOP14
