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 FK and J packages,
SN55188 chips are alloy mounted.
