1. General description

The LSF0101-Q100 is an 1 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 LSF0101-Q100 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.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
