Description
The PCA9546A is a quad bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream
pair fans out to four downstream pairs, or channels. Any individualSCx/SDx channel or combination of
channels can be selected, determined by thecontents of the programmable control register.An active LOW
reset input allows the PCA9546A to recover from a situation where one ofthe downstream I2C-buses is stuck
in a LOW state. Pulling the RESET pin LOW resetsthe I2C-bus state machine and causes all the channels
to be deselected as does theinternal Power-On Reset (POR) function.The pass gates of the switches are
constructed such that the VDD pin can be used to limitthe maximum high voltage which is passed by the
PCA9546A. This allows the use ofdifferent bus voltages on each pair, so that 1.8 V or 2.5 V or 3.3 V parts
can communicatewith 5 V parts without any additional protection. External pull-up resistors pull the bus upto
the desired voltage level for each channel. All I/O pins are 5 V tolerant
Features
- 1-of-4 bidirectional translating switches
- I2C-bus interface logic; compatible with SMBus standards
- Active LOW reset input 3 address pins allowing up to 8 devices on the I2C-bus
- Channel selection via I2C-bus, in any combination
- Power-up with all switch channels deselected
- Low Ron switches Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses
- No glitch on power-up Supports hot insertion
- Low standby current Operating power supply voltage range of 2.3 V to 5.5 V
- 5 V tolerant Inputs 0 Hz to 400 kHz clock frequency
- ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM perJESD22-C101
- Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
- Three packages offered: SO16, TSSOP16, and HVQFN16
