Application Note

Schematic Checklist - A Guide to Designing With Fixed or Direction Control Translators

Abstract

This application note provides recommendations and a checklist to follow while creating or reviewing schematics for fixed-directional or direction-control level shifters. Examples of such devices are the TXU, TXV, LXC, LVC, AXC, AVC, AUP, LVxT devices.

1 Introduction

TXU, TXV, LXC, LVC, AXC, AVC, AUP, LVxT device families are recommended for unidirectional applications where individual channels are used for a fixed directional signal. TXS, TXB and LSF families are recommended for applications that require auto-bidirection with individual channels. Section 1.2 shows examples of fixed directional signals and auto-bidirectional signals.
