NLSX3378/D
NLSX3378
4-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX3378 is a 4ïbit configurable dualïsupply bidirectional
auto sensing translator that does not require a directional control pin.
The V
CC
I/O and V
L
I/O ports are designed to track two different
power supply rails, V
CC
and V
L
respectively. The V
CC
supply rail is
configurable from 1.65 V to 4.5 V while V
L
supply rail is
configurable to 1.2 V to 4.1 V. This allows lower voltage logic
signals on the V
L
side to be translated into higher voltage logic
signals on the V
CC
side, and viceïversa.
The NLSX3378 translator has openïdrain outputs with integrated
10 kW pullup resistors on the I/O lines. The integrated pullup
resistors are used to pullup the I/O lines to either V
L
or V
CC
. The
NLSX3378 is an excellent match for openïdrain applications such as
the I
2
C communication bus.
