NLSV8T244
8-Bit Dual-Supply Non-
Inverting Level Translator
The NLSV8T244 is a 8−bit configurable dual−supply voltage level
translator. The input A
n
and output B
n
ports are designed to track two
different power supply rails, V
CCA
and V
CCB
respectively. Both
supply rails are configurable from 0.9 V to 4.5 V allowing universal
low−voltage translation from the input A
n
to the output B
n
port.
