描述 Description

The NLSX4401 is a 1?bit configurable dual?supply bidirectional
auto sensing translator that does not require a directional control pin.
The I/O VCC and I/O VL ports are designed to track two different
power supply rails, VCC and VL respectively. Both the VCC and VL
supply rails are configurable from 1.5 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 NLSX4401 translator has integrated 10 k\u0002 pull?up resistors
on the I/O lines. The integrated pull?up resistors are used to pull up
the I/O lines to either VL or VCC. The NLSX4401 is an excellent
match for open?drain applications such as the I2C communication
bus.
