PCA9848 Datasheet PDF (8-channel ultra-low voltage Fm+ I2C-bus switch)

PCA9848 - 8-channel ultra-low voltage Fm+ I2C-bus switch

Description

The PCA9848 is an ultra-low voltage, octal bidirectional translating switch controlled via the I2C-bus.

The SCL/ SDA upstream pair fans out to eight downstream pairs, or channels.

Any or all SCx/SDx channels can be selected, determined by the programmable control register.

Features

Ultra-low voltage operation, down to 0.8 V to interface with next-generation CPUs.
1-of-8 bidirectional translating switch.
Fm+ I2C-bus interface logic; compatible with SMBus standards.
Active LOW reset input.
Two address pins allow up to 16 devices on the I2C-bus.
Channel selection via I2C-bus.
Power-up with all switch channels deselected.
Low Ron switches.
Allows voltage level translation between 0.8 V, 1.8 V, 2.

PCA9848 8-channel ultra-low voltage, Fm+ I2C-bus switch with reset Rev. 2.0 — 16 May 2023 Product data sheet 1 General description The PCA9848 is an ultra-low voltage, octal bidirectional translating switch controlled via the I2C-bus. The SCL/ SDA upstream pair fans out to eight 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 PCA9848 to recover from a situation where one of the downstream I2Cbuses is stuck in a LOW state.
