ELECTROSTATIC DISCHARGE PROTECTION

SN65HVD179

SLLS668A – FEBRUARY 2006 – REVISED MAY 2006

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

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.

(2)

All voltage values, except differential I/O bus voltages, are with respect to network ground terminal.

This tests survivability only and the output state of the receiver is not specified.

The Thermal shutdown of this device internally limits the continuous total power dissipation. Thermal shutdown typically occurs when the

junction temperature reaches 165

°C.
