Additional preview pages of the TDA8034HN datasheet.

The TDA8034HN is a cost-effective analog interface for asynchronous and synchronous smart cards operating at 5 V, 3 V or 1.8 V.

Using few external components, the TDA8034HN provides all supply, protection and control functions between a smart card and the microcontroller.

Integrated circuit smart card interface in an HVQFN24 package.
5 V, 3 V or 1.8 V smart card supply.
Very low power consumption in Deep Shutdown mode.
Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8).
VCC regulation:.
5 V, 3 V or 1.8 V  5 % using two low ESR multilayer ceramic capacitors: one of 220 nF and one of 470 nF.
current spikes of 40 nA/s (VCC = 5 V and 3 V) or 15 nA/s (VCC =1.8 V) up to 20 MHz, with controlled rise and fall.
