NLSX3373
2-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX3373 is a 2−bit configurable dual−supply bidirectional
auto sensing translator that does not require a directional control pin.
The V I/O and V I/O ports are designed to track two different

configurable from 1.65 V to 4.5 V while V supply rail is
configurable to 1.2 V to 4.1 V. This allows lower voltage logic

signals on the V side, and vice−versa.
The NLSX3373 translator has open−drain outputs with integrated
10 kW pullup resistors on the I/O lines. The integrated pullup
