NLSX3378
4-Bit 20 Mb/s Dual-Supply
Level Translator
The NLSX3378 is a 4−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

The NLSX3378 translator has open−drain outputs with integrated
10 kW pullup resistors on the I/O lines. The integrated pullup
resistors are used to pullup the I/O lines to either V or V . The
