The NLSV4T244 is a 4 bit configurable dual supply voltage level translator. The input An and output Bn ports are designed to track two different power supply rails, VCCA and VCCB respectively. Both supply rails are configurable from 0.9 V to 4.5 V allowing universal low voltage translation from the input An to the output Bn port

VCCA and VCCB Operating Range: 0.9 V to 4.5 V
High-Speed w/ Balanced Propagation Delay
Inputs and Outputs have OVT Protection to 4.5 V
Non-preferential VCCA and VCCB Sequencing
Outputs at 3-State until Active VCC is Reached
Power-Off Protection
Outputs Switch to 3-State with VCCB at GND
Ultra-Small Packaging: 1.7 mm x 2.0 mm UQFN12
This is a Pb-Free Device
