DESCRIPTION/ORDERING INFORMATION
TPD5S116 is a single-chip HDMI interface device with auto-direction sensing I2C voltage level shift buffers, 5V
HDMI compliant current limited load switch, hot-plug-detect, and integrated ESD protection clamps for all
connector side pins. The device pin mapping can be routed to either HDMI Type D or Type C connector. An
internal 3.3V node powers the CEC pin, eliminating the need for a 3.3V supply on board.
TPD5S116 integrates all external termination resistors at the HPD, CEC, SCL, and SDA lines. There are three
non-inverting bi-directional translation circuits for the SDA, SCL, and CEC lines. Each has a common power rail
(VCCA) on system side from 1.1 V to 3.6V. A 55mA current limiting switch regulates current sent from 5V_SYS
to 5V_CON. The SCL and SDA pins meet the I2C specification and can drive up to 750 pF capacitive loads,
which exceeds HDMI1.4 specifications. The HPD_CON port has a glitch filter to avoid false detection due to plug
bouncing during the HDMI connector insertion.
The TPD5S116 offers reverse current block at the 5V_CON pin. In fault conditions, such as when two HDMI
transmitters are connected to the same HDMI cable, TPD5S116 ensures that the system is safe from powering
up through external HDMI transmitter. The SCL_CON, SDA_CON, CEC_CON pins also feature reverse-current
blocking, which ensures that the system sees no leakage if an HDMI receiver is connected while the system if
powered off.
The EN pin enables the hot-plug detect and load switch. The level shifters are enabled after a valid HPD signal is
detected.
