Fonctionnalités et applications
The PCA9545A is a 1-of-4 bidirectional 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, INT0 to INT3, one for each of the SCx/SDx downstream pairs, are provided. One interrupt output, INT, which acts as an AND of the four interrupt inputs, is provided.

A power-on reset function puts the registers in their default state and initializes the I2C-bus state machine with no channels selected.

Features:

  • 1-of-4 bidirectional translating multiplexer
  • I2C-bus interface logic; compatible with SMBus
  • 4 active LOW interrupt inputs
  • Active LOW interrupt output
  • 3 address pins allowing up to 8 devices on the I2C-bus
  • Channel selection via I2C-bus
  • Power-up with all multiplexer channels deselected
  • Low Ron switches
  • Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses
  • No glitch on power-up
  • Supports hot insertion
  • Low standby current
