PCA9545A Datasheet | NXP Semiconductors

4-channel I2C-bus switch with interrupt logic and reset Rev. 10 - 27 September 2022 Product data sheet 1 General description The PCA9545A is a quad bidirectional translating switch controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individual SCx/SDx channel or bination of channels can be selected, determined by the contents of the programmable control register. Four interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output, INT, acts as an AND of the four interrupt inputs. An active LOW reset input allows the PCA9545A to recover from a situation where one of the downstream...
