LSF0108 8-bit bidirectional multi-voltage level translator open-drain push-pull Rev. 1 18 September 2019 Product data sheet 1. General description The LSF0108 is an 8 Channel bidirectional multi-voltage level translator for open-drain and push-pull applications. It supports up to 100 MHz up translation and 100 MHz down translation at 30 pF capacitive load. There is no need for a direction pin which minimizes system effort. The LSF0108 supports 5 V tolerant I/O pins for compatibility with TTL levels in a variety of applications. The ability to set up different voltage translation levels on each channel makes the device very flexible and suitable for a lot of different applications. 2.
