PCA9306

Dual bidirectional I2C-bus and SMBus voltage-level translator

• Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and Fast-mode I2C-bus

devices and multiple controllers

• Allows voltage level translation between:

– 1.0 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2)

– 1.2 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2)

– 1.8 V Vref(1) and 3.3 V or 5 V Vbias(ref)(2)

– 2.5 V Vref(1) and 5 V Vbias(ref)(2)

– 3.3 V Vref(1) and 5 V Vbias(ref)(2)

• Provides bidirectional voltage translation with no direction pin

• Low 3.5 Ω ON-state connection between input and output ports provides less signal distortion

• Open-drain I2C-bus I/O ports (SCL1, SDA1, SCL2 and SDA2)

• 5 V tolerant I2C-bus I/O ports to support mixed-mode signal operation

• High-impedance SCL1, SDA1, SCL2 and SDA2 pins for EN = LOW

• Lock-up free operation

• Flow through pinout for ease of printed-circuit board trace routing

• ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101

• Packages offered: SO8, TSSOP8, VSSOP8, XQFN8, XSON8, X2SON8
