3 Description
The LSF0102-Q1 device is an auto bidirectional
voltage translator that translates among a wide range
of supplies without the need for a directional pin. The
LSF0102-Q1 supports up to 100 MHz up translation
and greater than 100 MHz down translation with
capacitive loads ≤ 30 pF. Additionally, the LSF0102-
Q1 supports up to 40 MHz up and down translation at
50 pF capacitance load, which enables the LSF0102-
Q1 device to support a wide variety of standard
interfaces commonly found in automotive applications
such as I2C, SPI, GPIO, SDIO, UART, and MDIO.
The LSF0102-Q1 device has 5-V tolerant data inputs.
This makes the device compatible with TTL voltage
levels. Furthermore, the LSF0102-Q1 supports mixedmode
voltage translation, allowing the device to up
translate and down translate to different supply levels
on each channel.
