LTC4307-1
APPLICATIONS INFORMATION
Figure 4 shows the LTC4307-1 being used for capacitance Although the applications shown in this section are for buffering and 5V to 3.3V level shifting. In this application, HDMI receive channels, the LTC4307-1 can also be used the EEPROM is powered by a backup 3.3V supply that is in HDMI transmit channels with equal success as shown available when the component is turned off. The EDID in in the Typical Application on the last page of this data the EEPROM should be available for reading even when sheet. a component’s power is off.
