LSF0102DC集成电路（IC）的转换器电平移位器规格书PDF中文资料

1. General description

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 ≥100 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.
