Notes:
1. Time from transmit is enabled (V_Tx-en is set to logic high) until output (Tx-PD-out) is available. See Figure 18 in the Application Information section.
2. Time from output (Tx-PD-out) is available until Tx-PD-out signal reaches 66% of its steady state level. See Figure 18 in the Application Information
section.
3. To keep the junction temperature as close to the ambient temperature as possible, pulse testing method is used. The device is transmit-enabled within
the pulse duration time, t_P. Thermal effects must be considered separately.
4. Maximum power dissipation in Control side and Line side IC's needs to be limited to ensure that their respective junction temperature is less than 125°C.
The maximum permissible power dissipation is dependent on the thermal impedance and the ambient temperature. Details on the typical thermal
impedances are given in the Package Characteristics. Further details on applying this to an actual application can be found in the Application Information
section under Thermal Considerations.
