11. Application information

11.1 Special considerations

Certain cable or dongle misplug scenarios make it possible for a 5 V input condition to

occur on pins AUX+ and AUX

−, as well as HPDIN. When AUX+ and AUX− are connected

through a minimum of 2.2 k

Ω resistor each, the CBTL06DP211 will sink current but will not

be damaged. Similarly, HPDIN may be connected to 5 V via at least a 1 k

Ω resistor.

(Correct functional operation to specification is not expected in these scenarios.) The

latter also prevents the HPDIN input from loading down the system HPD signal when

power to the CBTL06DP211 is off.
