LSF0102DCH

The LSF0102 is a 2 channel bidirectional multi-voltage level translator for open-drain and push-pull applications. It supports up to 100 MHz up translation and 2100 MHz down translation at ≤30 pF capacitive load. There is no need for a direction pin which minimizes system effort. The LSF0102 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.
