Working Principles

The 74LVTH125D,118 is a quad buffer/line driver IC designed to perform voltage level translation between different logic families. It operates by receiving input signals from one logic family and translating them into output signals compatible with another logic family. The device utilizes a combination of MOSFETs and CMOS technology to achieve high-speed operation and low power consumption.

The IC features 3-state outputs, which allow multiple devices to share a common bus without causing conflicts. When the output enable (OE#) pin is set to a high logic level, the outputs are in a high-impedance state, effectively disconnecting the device from the bus.
