LSF0204 4-bit bidirectional multi-voltage level translator open-drain push-pull Rev. 2 28 October 2020 Product data sheet 1. General description The LSF0204 is an 4 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 LSF0204 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.
