8 Detailed Description

8.1 Overview

The LSF0108-Q1 can be used in level-translation applications for interfacing devices or systems operating

at different supply voltages. The LSF0108-Q1 is ideal for use in applications where an open-drain driver is

connected to the data I/Os. LSF0108-Q1 can achieve 100 MHz with appropriate pull-up resistors and layout. The

LSF0108-Q1 may also be used in applications where a push-pull driver is connected to the data I/Os. For an

overview of device setup and operation, see The Logic Minute training series on Understanding the LSF Family

of Bidirectional, Multi-Voltage Level Translators.
