NLSX4378ABFCT1G

The NLSX4378A 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 and VL supply rails are configurable from 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 NLSX4378A translator has open−drain outputs with integrated 10 kΩ 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 NLSX4378A is an excellent match for open−drain applications such as the I²C communication bus.
