Control registers for conference call between one IOM buffer and two PSTN lines
14 LIMITING VALUES
Limiting values in accordance with the Absolute Maximum Rating System (IEC 134).
15 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. ESD protection according to Human
Body Model is guaranteed up to 2 kV. However, to be totally safe, it is desirable to take normal precautions appropriate
to handling MOS devices (see “Handling MOS Devices”).
