This is a breakout board for the PCA9306 dual bidirectional voltage-level translator. Because different parts sometimes use different voltage levels to communicate, voltage level translators can be the key to making different parts play nice.The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator that's operational on the low side from 1.0 V to 3.6 V and on the high side from 1.8 V to 5.5 V. Simply apply your low- and high-side reference voltages to the VREF1 and VREF2 respectively, connect your I/O and drive the Enable pin high to open bidirectional voltage translation without the use of a direction pin! _x000D_ _x000D_ Features: _x000D_ 2-bit bidirectional translator for SDA and SCL lines in mixed-mode I2C-bus applications _x000D_ Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus and SMBus compatible _x000D_ Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and Fast-mode I2C-bus devices and multiple masters _x000D_ Allows voltage level translation between: 1.0 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias; 1.2 V Vref(1)and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias;1.8 V Vref(1)and 3.3 V or 5 V Vbias; 2.5 V Vref(1) and 5 V Vbias; 3.3 V Vref(1) and 5 V Vbias _x000D_ Provides bidirectional voltage translation with no direction pin _x000D_ Low 3.5 ON-state connection between input and output port provides less signal distortion _x000D_ _x000D_ Specification: _x000D_ Model:PCA9306 _x000D_ Type:Level Translator Breakout _x000D_ Color:red _x000D_ _x000D_ Package list: _x000D_ 1 x PCA9306 breakout board _x000D_
