Product Overview NLSX4378: Level Translator, 4-Bit, 24 Mbps, Dual-Supply For complete documentation, see the data sheet Product Description The NLSX4378 is a 4-Bit configurable dual-supply bidirectional auto sensing translator that does not require a directional control pin. The V<sub>CC</sub> I/O and V<sub>L</sub> I/O ports are designed to track two different power supply rails, V<sub>CC</sub> and V<sub>L</sub> respectively. The V<sub>CC</sub> Supply rail is configurable from 1.65V to 5.5V while the V<sub>L</sub> supply rail is configurable from 1.65V to 5.5V. This allows voltage logic signals on the V<sub>L</sub> side to be translated into lower, higher or equal value voltage logic signals on the V<sub>CC</sub> side, and vice-versa. The NLSX4378 translator has integrated 10K ohm pullup resistors on the I/O lines. The integrated pullup resistors are used to pullup the I/O lines to2 either V<sub>L</sub> or V<sub>CC</sub>. The NLSX4378 is an excellent match for open-drain applications such as the I C communication bus.
