PCA9518 Expandable 5channel I2

The PCA9518 is a BiCMOS integrated circuit intended forapplication in I2C and SMBus systems.While retaining all the operating modes and features of the I2Csystem, it permits extension of the I2C-bus by buffering both thedata (sda) and the clock (SCL) lines, thus enabling virtuallyunlimited buses of 400 pF.

PCA9540B 2channel I2C bus mult

The PCA9540B 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 theprogrammable control register.

PCA9519 4channel level transla

The PCA9519 is a 4-channel level translating I2C-bus/SMBus repeater that enables theprocessor low voltage 2-wire serial bus to interface with standard I2C-bus or SMBus I/O.While retaining all the operating modes and features of the I2C-bus system during thelevel shifts, it also permits extension of the I2C-bus by providing bidirectional buffering forboth the data (sda) and the clock (SCL) lines, thus enabling the I2C-bus or SMBusmaximum capacitance of 400 pF on the higher voltage side. The sda and SCL pins areover-voltage tolerant and are high-impedance when the PCA9519 is unpowered.

PCA9519 4通道I2C-bus SMBus 中繼器

PCA9519 是一個4 通道的I2C 總線/SMBus 中繼器，可以實現將低電壓兩線串行總線接口的處理器與標準的I2C 總線或SMBus I/O 相連。該中繼器在電平轉換中保持I2C 總線系統所有的模式和特點的同時，允許通過給數據總線（sda）和時鐘總線（SCK）提供雙向緩沖區來擴展I2C 總線，從而使I2C 總線或SMBus 在高電壓下最大容限電容為400PF。sda 和SCL 引腳具有耐壓保護功能，當PCA9519 掉電時，均呈現出高阻抗特性。

PCA9542A 2channel I2C bus mult

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 theprogrammable control register. Two interrupt inputs, INT0 and INT1, one for each of theSCx/SDx downstream pairs, are provided. One interrupt output, INT, which acts as anAND of the two interrupt inputs, is provided.
