LSF0108BQ数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 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. TheLSF0108 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.
