***eco: I2C INTERFACE <AZ

***AS INSTRUMENTS INC: The PCA9544A is a 4-channel, bidirectional translating multiplexer controlled via the I2C bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. One SCL/SDA pair can be selected at a time, and this is determined by the contents of the programmable control register. Four interrupt inputs ( INT3– INT0), one for each of the downstream pairs, are provided. One interrupt output ( INT) acts as an AND of the four interrupt inputs.

***AS: A power-on reset function puts the registers in their default state and initializes the I2C state machine, with no channel selected.

***AS INSTRU: 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 PCA9544A. This allows the use of different bus voltages on each 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.

PCA9544ARGYR More Information

PCA95xx I²C, SMBus Repeaters, Switches, Expanders: OMO Electronic PCA95xx I²C and SMBus devices consist of a variety of logic ICs, including repeaters, bidirectional translating switches, and I/O expanders. The TI PCA9515A dual bidirectional I²C and SMBus repeater is a BiCMOS IC intended for I²C and SMBus systems applications. The PCA9515A contains two identical bidirectional open-drain buffer circuits that enable I²C and similar bus systems to be extended without degradation of system performance. The TI PCA9544A and PCA9545A are quad bidirectional translating switches controlled via the I²C bus. The SCL/SDA upstream pair on the PCA9544A and PCA9545A fans out to four downstream pairs, or channels On the PCA9544a, one SCL/SDA pair can be selected at a time, and this is determined by the contents of the programmable control register. On the PCA9545A, any individual SCn/SDn channel or combination of channels can be selected, and this is determined by the contents of the programmable control register. The TI PCA9554A and PCA9557 are remote 8-bit I²C and SMBus expanders. The PCA9554A and PCA9557 provide general-purpose I/O expansion for most microcontroller families via the I²C interface.Learn More
