TDA8034T - Smart Card Interface

Download the TDA8034T datasheet PDF. This datasheet also covers the TDA8034AT variant, as both devices belong to the same smart card interface family and are provided as variant models within a single manufacturer datasheet.

General Description

The TDA8034T/TDA8034AT is a cost-effective analog interface for asynchronous and synchronous smart cards operating at 5 V or 3 V.

Using few external components, the TDA8034T/TDA8034AT provides all supply, protection and control functions between a smart card and the microcontroller.
