STMicroelectronics 74LVX125MTR: Low Voltage Quad Buffer with 3-STATE Outputs

The 74LVX125MTR from STMicroelectronics is a high-performance, low-voltage CMOS quad buffer designed to operate as a non-inverting buffer. This integrated circuit is part of the 74LVX family, which is characterized by its low power consumption and high speed, making it an ideal choice for a wide range of applications, including mobile, computing, and consumer electronics.

With its advanced 3.3V technology, the 74LVX125MTR is optimized to work in systems that require low power dissipation and high noise immunity. The device features four independent buffer gates, each with a 3-STATE output that can be placed in a high impedance state. This is particularly useful in bus-oriented applications where multiple devices need to share a common data or address bus.

The 74LVX125MTR operates over a broad voltage range of 2.0V to 3.6V, which provides a great deal of flexibility in terms of compatibility with other logic families. Its input levels are compatible with 5V systems, allowing it to interface with older logic families seamlessly. This makes the 74LVX125MTR a versatile choice for bridging the gap between different voltage domains in mixed-voltage systems.

Packaged in a compact and efficient TSSOP-14 package, the 74LVX125MTR is designed to occupy minimal board space while providing robust performance. The device's inputs and outputs are equipped with protection circuits against static discharge, giving it resilience in physically demanding environments.

Key features of the 74LVX125MTR include:

• Low voltage operation: 2.0V to 3.6V
• High-speed performance: t<sub>PD = 4.2ns (MAX) at V<sub>CC = 3.3V
• Power-down protection on inputs and outputs
• 4-bit non-inverting buffer logic with 3-STATE outputs
• 5V tolerant inputs for interfacing with 5V logic levels
• Low quiescent current: I<sub>CC = 2µA (MAX)
• Supports live insertion and withdrawal (partial power-down)
• Lead-free, halogen-free, and RoHS compliant

The STMicroelectronics 74LVX125MTR is an excellent choice for designers looking for a reliable, low-power buffer with the flexibility to fit into a variety of digital applications while maintaining signal integrity in a small form factor.
