8 Detailed Description

8.1 Overview

The LSF family can be used in level-translation applications for interfacing devices or systems operating with one

another, that operate at different interface voltages. The LSF family is ideal for use in applications where an

open-drain driver is connected to the data I/Os. With appropriate pull-up resistors and layout, LSF can achieve

100 MHz. The LSF family can 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.
