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

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.
