STMicroelectronics 74LCX125TTR Low Voltage Quad Buffer

The 74LCX125TTR is a high-performance, low-voltage quad buffer designed by STMicroelectronics, renowned for its commitment to innovation and quality in the semiconductor industry. This integrated circuit is part of the LCX family, which is specifically engineered to operate with a low power supply range while maintaining the capability to interface with a wide range of voltage levels. This makes it an ideal choice for mixed-voltage applications and for interfacing with 5V systems.

Each of the four buffers in the 74LCX125TTR has a separate output enable input, which facilitates the use of this device as a line driver or bus holder. When the output enable input is high, the output is in a high impedance state, allowing for the connection of multiple outputs to a bus without the risk of damaging the device or creating bus contention.

The device is characterized for operation from -40°C to +85°C, making it suitable for industrial temperature ranges. Its robust design ensures reliable operation even under challenging environmental conditions. The 74LCX125TTR comes in a TSSOP package, which is a space-saving option for PCB design, offering a compact footprint while ensuring good thermal performance.

Key features of the STMicroelectronics 74LCX125TTR include:

• Low voltage operation: 2.3V to 3.6V
• 5V tolerant inputs and outputs for interfacing with 5V logic levels
• High-speed performance, with propagation delays typically less than 5.0 ns
• Low quiescent current consumption, which is ideal for power-sensitive applications
• Power-down high impedance inputs and outputs
• Support for live insertion and withdrawal (hot swapping)
• Lead-free, RoHS-compliant, and 100% tested for quiescent current at 20V

The 74LCX125TTR is an exemplary solution for designers looking for a reliable, low-voltage buffer with the flexibility to interface with various logic levels. Its performance and power efficiency make it a go-to component for a multitude of applications, including computing, telecommunications, and consumer electronics. STMicroelectronics' dedication to quality ensures that this buffer meets the highest standards, providing a dependable and efficient solution for digital logic circuit designs.
