Overview
NLSX4378 4-Bit 20 Mb/s Dual-Supply Level Translator The NLSX4378 is a 4−bit configurable dual−supply bidirectional auto sensing translator that does not require a directional control pin.
The VCC I/O and VL I/O ports are designed to track two different power supply rails, VCC and VL respectively.
The VCC supply rail is configurable from 1.
65 V to 5.
5 V while VL supply rail is configurable to 1.
65 V to 5.
5 V.
This allows voltage logic signals on the VL side to be translated into lower, higher or equal value voltage logic signals on the VCC side, and vice−versa.
The NLSX4378 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 VL or VCC.
The NLSX4378 is an excellent match for open−drain applications such as the I2C communication bus.
