SIM card interface level translator with enable pin

Description

The NXT4558 device is built for interfacing a SIM card with a single low-voltage host side interface. The NXT4558 has three level translators to convert the data, RST and CLK signals between a SIM card and a host microcontroller. A high-speed level translation capable of supporting class-B, class-C SIM cards. An active HIGH EN pin enables normal operation of the translator. A HIGH to LOW transition on pin EN initiates a shutdown sequence on SIM card pins in accordance with ISO-7816-3.
