PCA9544PWDH規(guī)格書詳情
DESCRIPTION
The PCA9544 is a 1-of-4 bi-directional translating multiplexer, controlled via the I2C bus. The SCL/SDA upstream pair fans out to four 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. Four interrupt inputs, one for each of the SCx/SDx downstream pair, are provided. One interrupt output, which acts as an AND of the four interrupt inputs, is provided. All I/O pins are 5 V tolerant.
