NLSV4T3234
4−Bit Dual−Supply Bus
Buffer Level Translator with
26 W Output Series Resistor
The NLSV4T3234 is a 4−bit configurable dual−supply voltage level
translator. The input (B−) and output (A−) ports are designed to track

two different power supply rails, V
and V
respectively. Both

supply rails are configurable from 0.9 V to 4.5 V, allowing
high−to−low and low−to high voltage translation from the input (B−)
to the output (A−) port.
The NLSV4T3234 is a low power voltage translator that contains
series output resistors, and overvoltage tolerant (OVT) input and
output protection. The 26 W series resistor on the output drivers
minimizes ringing on the logic transition edges. The OVT feature
allows the NLSV4T3234 to translate input signals greater than the
