Nexperia NXT455x SIM Card Interface Level Translators

Nexperia NXT455x SIM Card Interface Level Translators are designed for interfacing a SIM card with a single low-voltage host-side interface. These devices feature three level translators to convert the data, RST, and CLK signals between a SIM card and a host microcontroller. The NXT455x SIM card interface level translators support SIM cards and eSIM with supply voltages ranging from 1.62V to 3.3V. These devices include integrated pull-up resistors, eliminating the need for external resistors. The NXT455x SIM card interface level translators feature a low current shutdown mode of less than 1μA. These devices comply with all ETSI, IMT-2000, and ISO-7816 SIM/smart card interface requirements.

The NXT455x SIM card interface level translators operate within the -40°C to 85°C temperature range. These devices are EC/CN RoHS-compliant. Typical applications include mobile and personal phones, wireless modems, and SIM card terminals.

Features

Support SIM cards and eSIM with supply voltages from 1.62V to 3.3V
1.08V to 1.98V host micro-controller operating voltage range
Automatic level translation of I/O, RST, and CLK between SIM card and host side interface with capacitance isolation
