NLSX3014
4-Bit 100 Mb/s Configurable
Dual-Supply Level
Translator
The NLSX3014 is a 4−bit configurable dual−supply bidirectional
level translator without a direction control pin. The I/O V
CC
−
and I/O
V
L
−ports
are designed to track two different power supply rails, V
CC
and V
L
respectively. The V
CC
supply rail is configurable from 1.3 V
to 4.5 V while the V
L
supply rail is configurable from 0.9 V to (V
CC
−
0.4) 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
vice−versa. Both I/O ports are auto−sensing; thus, no direction pin is
required.
The Output Enable (EN) input, when Low, disables both I/O ports
by putting them in 3−state. This significantly reduces the supply
currents from both V
CC
and V
L
. The EN signal is designed to track
V
L
.
