† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to the network ground terminal.

2. For operation above 25

°C free-air temperature, refer to the maximum supply voltage curve, Figure 6. In the J package, SN55188

chips are alloy mounted.

3. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable

ambient temperature is PD = (TJ(max) − TA)/θJA. Selecting the maximum of 150°C can affect reliability.

4. The package thermal impedance is calculated in accordance with JESD 51-7.
