9.1 Overview

The LSF Family may be used in level translation applications for interfacing devices or systems operating at different interface voltages with one another. The LSF Family is ideal for use in applications where an open-drain driver is connected to the data I/Os. LSF can achieve 100 MHz with the appropriate pull-up resistors and layout. The LSF Family may also be used in applications where a push-pull driver is connected to the data I/Os.
