Features
2-Bit bidirectional translator for SDA and SCL in mixed-mode I2C applications
I2C and SMBus compatible
Less than 1.5ns maximum propagation delay to accommodate standard-mode and fast-mode I2C devices and multiple masters
Allows voltage-level translation between
– 1.2V VREF1 and 1.8V, 2.5V, 3.3V, or 5V VREF2
– 1.8V VREF1 and 2.5V, 3.3V, or 5V VREF2
– 2.5V VREF1 and 3.3V or 5V VREF2
– 3.3V VREF1 and 5V VREF2
Provides bidirectional voltage translation with no direction pin
Low 3.5Ω ON-state resistance between input and output ports provides less signal distortion
5V tolerant I2C I/O ports to support mixed-mode signal operation
High-impedance SCL1, SDA1, SCL2, and SDA2 pins for EN = Low
Lockup-free operation for isolation when EN = Low
Flow-through pin out for ease of printed-circuit-board trace routing
Applications
I2C, SMBus, PMBus, MDIO, UART, low-speed SDIO, GPIO, and other two-signal interfaces
Servers
Routers (Telecom Switching Equipment)
