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, VCCB and VCCA 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
input power supply VCCB and protects the IC from damage if a signal
is connected to an output pin that is greater than VCCA.
Features
Wide VCCA and VCCB Operating Range: 0.9 V to 4.5 V
High−Speed Logic Voltage Translation
26 W Series Resistors on Outputs (A−) Reduce Ground Bounce and
Overshoot
Overvoltage Tolerant (OVT) Inputs and Outputs to 4.5 Vwww.DataSheet4U.com
Non−preferential Power Supply Sequencing
Outputs At 3−State Until Active VCC Is Reached
Outputs Switch to 3−State with VCCA at GND
Ultra−Small Packaging: 1.41 mm x 2.04 mm Flip−Chip11
RoHS Compliant
This is a Pb−Free Device*
