            PCA9848PW 8-Channel Switch
                    NXP offers its PCA9848PW 8-channel ultra-low-voltage, Fm+ I²C bus switch with reset
    

Image of NXP's PCA9848PW 8-Channel Switch NXP's 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.

Features and Benefits
Ultra-low-voltage operation, down to 0.8 V to interface with next-generation CPUs One-of-eight bidirectional translating switch Fast-mode Plus (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 Low R_ON switches Allows voltage level translation between 0.8 V, 1.8 V, 2.5 V, and 3.3 V buses Reset via I²C bus software command		I²C Device ID function No glitch on power-up Supports hot insertion since all channels are deselected at power on Low standby current 3.6 V tolerant inputs 0 Hz to 1 MHz clock frequency ESD protection exceeds 6000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101 Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA Package offered: TSSOP24
Applications
Computing: I²C bus isolation in larger server platforms Industrial: enabling multiple slaves with the same I²C address		Commercial: obscuring I²C slaves for direct detection Automotive: protecting sensitive I²C master devices from overstress damage
