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.
