Abstract NXP Voltage Translators (NVT) are used in bidirectional signaling voltage
level translation applications for I/O buses with incompatible logic levels.
The NVT2001 and NVT2002 are single- and dual-channel voltage
translators, operational from 1.0 V to 3.6 V at V
1.8 V to 5.5 V at V
open-drain or push-pull I/O devices.

1. Introduction
The NVT2001GM (OM13315) and NVT2002DP (OM 13318) 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.
