RS7LS9306Q Bidirectional I2C-bus And SMBus Voltage-Level Translator
●The RS7LS9306Q is a dual bidirectional I²C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0 V to 3.3 V (VREF1) and 1.8 V to 5.5 V(VREF2).
●The RS7LS9306Q allows bidirectional voltage translations between 1.0 V and 5 V without the use of a direction pin. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. When EN is HIGH, the translator switch is on, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off, and a high- impedance state exists between ports.
●The RS7LS9306Q is not a bus buffer that provides both level translation and physically isolates to either side of the bus when both sides are connected. The RS7LS9306Q only isolates both sides when the device is disabled and provides voltage level translation when active.
●The translator provides excellent ESD protection to lower voltage devices, and at the same time protects less ESD-resistant devices.
■Features:
●2-bit bidirectional translator for SDA and SCL lines in mixed-mode I²C-bus applications
●Standard-mode, Fast-mode, and Fast-mode Plus I²C-bus and SMBus compatible
●Less than 1.5 ns propagation delay
●Allows voltage level translation between:
◆1.0 V VREF1 and 1.8 V～5 V VREF2
◆1.2 V VREF1 and 1.8 V～5 V VREF2
◆1.5 V VREF1 and 2.5 V～5 V VREF2
◆1.8 V VREF1 and 3.3 V～5 V VREF2
◆2.5 V VREF1 and 3.3 V～5 V VREF2
◆3.3 V VREF1 and 5 V VREF2
●Bidirectional voltage translation with no direction pin
●Low 3.5 ohm ON-state connection between input and output ports provides less signal distortion
●5 V tolerant I²C-bus I/O ports to support mixed-mode signal operation
●Lock-up free operation for isolation when EN = LOW
●Flow through pin out for ease of printed-circuit board trace routing
●ESD protection exceeds 4000V HBM
●AEC-Q100 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities.
●Extended Temperature: -40℃ to +105℃
