The 74LCX125MTCX is a low-voltage quad non-inverting buffer with 3-STATE outputs, fabricated with advanced CMOS technology for high-speed operation and low power dissipation. It operates over a wide VCC range from 1.65V to 5.5V and features 5V tolerant inputs and outputs, enabling the interface between 5V and 3V systems. The device provides a high output drive of ±24 mA at a 3.0V supply and achieves a maximum propagation delay of 6.0 ns at 3.3V. Key features include power-down high impedance on inputs and outputs, support for live insertion/withdrawal, and robust ESD protection. These characteristics make the 74LCX125MTCX ideal for bus buffering and logic-level translation applications in mixed-voltage environments.
