                      Product Overview

                      PCA9846PWJ is an ultra-low voltage, quad bidirectional translating switch controlled via the I²C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any or all SCx/SDx channels can be selected, determined by the programmable control register. This feature allows multiple devices with the same I²C-bus address to reside on the same bus. The switch device can also separate a heavily loaded I²C-bus into separate bus segments, eliminating the need for a bus buffer. An active LOW reset input allows the device to recover from a situation where one of the downstream I²C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets the I²C-bus state machine and deselects all the channels, as does the internal power-on reset (POR) function. The pass gates of the switches are constructed such that the VDD1 pin is used to limit the maximum high voltage which is passed by the PCA9846.

                      • Ultra-low voltage operation, down to 0.8V to interface with next-generation CPUs
                      • Fm+ I²C-bus interface logic; compatible with SMBus standards
                      • Active LOW reset input, 2 address pins allowing up to 16 devices on the I²C-bus
                      • Channel selection via I²C-bus, power-up with all switch channels deselected
                      • Reset via I²C-bus software command, I²C device ID function
                      • Supports hot insertion since all channels are de-selected at power-on
                      • No glitch on power-up, low standby current, 3.6V tolerant inputs
                      • Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
                      • Pass gate leakage current is +1µA maximum at (VSS = 0V; Tamb = -40°C to +85°C)
                      • Operating temperature range from -40°C to +85°C, TSSOP16 package
