Fonctionnalités et applications
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 the programmable control register.

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-2 bidirectional translating multiplexer
  • I2C-bus interface logic; compatible with SMBus standards
  • 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
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5 V tolerant inputs
  • 0 Hz to 400 kHz clock frequency
  • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD2-A115 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
  • Packages offered: SO8, TSSOP8
