The 74LVC125A is a high-performance, low-voltage CMOS quad buffer/line driver with 3-state outputs, designed for a wide range of digital applications. It is available in a 14-pin TSSOP (Thin Shrink Small Outline Package), making it suitable for compact circuit designs.

Features :

• Quad Non-Inverting Buffers: Provides four independent non-inverting buffers with individual output enable controls.
• 3-State Outputs: Each buffer has a 3-state output, allowing for high-impedance states when not in use.
• Wide Supply Voltage Range: Operates from 1.65 V to 5.5 V, accommodating various logic levels.
• 5.5 V Tolerant Inputs: Inputs can accept voltages up to 5.5 V, enabling interfacing with higher voltage systems.
• High Output Drive: Capable of sourcing and sinking 24 mA, suitable for driving moderate loads.
• Low Power Consumption: Features CMOS technology for low static power consumption.
• IOFF Support: Includes IOFF circuitry to prevent backflow current during power-down, supporting partial power-down applications.
• ESD Protection: Provides robust electrostatic discharge protection:
• Latch-Up Immunity: Exceeds 250 mA per JESD 78, Class II standards.
• Operating Temperature Range: -40°C to +125°C, suitable for industrial environments.
