SIM Card Interface Level Translator with EMI Filter and ESD Protection
NVT4557 Receive alerts
The NVT4557 device is built for interfacing a SIM card with a single low-voltage 1.08 V to 1.95 V host side interface. The NVT4557 contains three 1.65 V to 3.6 V level translators to convert the data, RSTn and CLKn signals between a SIM card and a host microcontroller.
The NVT4557 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/smart card interface requirements.
