Working Principles

The SN74LV125ATNSG4 is a non-inverting buffer/driver IC that operates as a voltage level shifter. It takes input signals from one logic family and provides output signals compatible with another logic family. The device has four independent channels, each capable of driving a single line.

The IC uses a combination of MOSFETs and CMOS technology to achieve its functionality. When the output enable (OE) pin is high, the outputs are in a high-impedance state, allowing multiple devices to share the same bus without interference. When OE is low, the inputs are buffered and transmitted to the outputs without inversion.
