LTC4307IMS8-1#PBF

LTC4307-1 is a high definition multimedia interface (HDMI) level shifting 2-wire bus buffer. It is a 2-wire bus buffer that provides capacitance buffering between input and output. The HDMI specification requires that devices have less than 50pF of input capacitance on their DDC bus lines. This device’s capacitance buffering features in conjunction with its sub-10pF data and clock input capacitance, allows HDMI components to easily meet the 50pF requirement and tolerate high capacitance on the internal bus. It also provides level-shifting between 3.3V and 5V systems to allow lower voltage HDMI transmitters, receivers and EEPROM to interface to the 5V DDC bus. READY is an open-drain digital output flag that indicates whether or not the input and output busses are connected and can interface to the HDMI hot plug detect (HPD) signal. It is used in applications such as HDMI, 3.3V/5V level translation, capacitance buffer/bus extender.
