MAX1840/MAX1841
Low-Voltage SIM/Smart Card
Level Translators in MAX

0V/3V/5V for full compatibility with SIM/smart-card specifi-
cations. Figure 2 shows the charge pump for SIM card
applications. Alternatively, the MAX619 generates a regu-
lated 5V from input voltages as low as 2V.
SPI/QSPI/MICROWIRE Interface
The MAX1840/MAX1841 are also useful as 3V/5V level
shifters in SPI, QSPI, and MICROWIRE applications
(Figure 3). On the slave side, connect CLK to SCLK,
RST to CS, and IO to DOUT and DIN. The unidirectional
level shifters transfer chip select and clock signals to
the slave device(s), while the bidirectional level shifter
transfers data.
