Abstract NXP Voltage Translators (NVT) are used in bidirectional signaling voltage
level translation applications for I/O buses with incompatible logic levels.
The NVT2008 and NVT2010 are eight- and ten-channel voltage
translators, operational from 1.0 V to 3.6 V at V
CC(A)
(low voltage side) and
1.8 V to 5.5 V at V
CC(B)
(high voltage side) without direction control for
open-drain or push-pull I/O devices.

NVT2008PW and NVT2010PW demo boards
1. Introduction
The NVT2008PW (OM13317) and NVT2010PW (OM13324) demo boards are designed
to let customers evaluate the NXP 8-channel and 10-channel bidirectional voltage level
translators. The demo boards interface between device I/Os operating at dif ferent voltag e
levels. Since the NVT2008PW and NVT2010PW 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 NVT2008PW and NVT2010PW devices allow
translations between any voltages from 1.0 V to 5.5 V.
Please refer to NVT2008/NVT2010 data sheet (Ref. 1
) and application note AN11127
(Ref. 2
) for more detailed information.
