NLSX4401DFT2G数据手册集成电路（IC）的转换器电平移位器规格书PDF

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.
