NVT2001GM and NVT2002DP demo boards

1. Introduction

The NVT2001GM (OM13315) and NVT2002DP (OM13318) demo boards are designed to 
evaluate the NXP 1-channel or 2-channel bidirectional voltage level translators. The demo 
boards interface between device I/Os operating at different voltage levels. Since the 
NVT2001GM and NVT2002DP devices are passive devices, pull-up resistors may be 
needed depending on the I/O interface type (totem pole or open-drain), difference in 
translation voltage, and the translation direction (high to low voltage, low to high voltage, 
or bidirectional). The NVT2001GM and NVT2002DP devices allow translations between 
any voltages from 1.0 V to 5.5 V.
