资料详细技术说明
The PCA9519 is a 4-channel level translating I2C-bus/SMBus repeater that enables the
processor 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 the
level shifts, it also permits extension of the I2C-bus by providing bidirectional buffering for
both the data (SDA) and the clock (SCL) lines, thus enabling the I2C-bus or SMBus
maximum capacitance of 400 pF on the higher voltage side. The SDA and SCL pins are
over-voltage tolerant and are high-impedance when the PCA9519 is unpowered.
