Dual-channel bidirectional multi-voltage level translator supports mix of standard interfaces
The LSF0102-Q1 device, from Texas Instruments, is an auto bidirectional voltage translator that translates among a wide range of supplies without the need for a directional pin. The device supports up to 100MHz up translation and greater than 100MHz down translation with capacitive loads =30pF. Also, the device supports up to 40MHz up and down translation at 50pF capacitance load, which allows it to support a broad mix of standard interfaces commonly found in automotive applications such as I2C, SPI, GPIO, SDIO, UART, and MDIO.
The device has 5V tolerant data inputs. This makes the device compatible with TTL voltage levels. Furthermore, the device supports mixed-mode voltage translation, enabling the device to up translate and down translate to different supply levels on each channel.
