Preliminary specification

Low-power (3 V/5 V) smart card coupler

TDA8005A

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is

desirable to take normal precautions appropriate to handling MOS devices.
