NLSX4302E
2-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX4302E is a 2−bit configurable dual−supply 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. Both the V
CC
and V
L
supply rails are configurable from 1.5 V to 5.5 V. This allows voltage
logic signals on the V
L
side to be translated into lower, higher or
equal value voltage logic signals on the V
CC
side, and vice−versa.
The NLSX4302E translator uses external pull−up resistors on the
I/O lines. The external pull−up resistors are used to pull up the I/O
lines to either V
L
or V
CC
. The NLSX4302E is an excellent match for
open−drain applications such as the I
2
C communication bus.
