These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION CONTINUED
With standard TMDS terminations at the outputs, all TMDS outputs are forced high-impedance when OE is set
high. The I
2
C repeater isolates the buses without accumulating the capacitance of both sides. It allows DDC
capacitance to be controlled under the desired load. The I
2
C outputs are high-impedance when device supply
voltage is less than 1.5 V or I2CEN is low. The OVS pin, output voltage select, provides the flexibility of adjusting
the output voltage level of the TSCL and TSDA side to optimize noise margins while interfacing to different HDMI
receivers. The device is characterized for operation from 0°C to 70°C.
