SKU: 000383 Categories: , Tags: , , , ,


The 74LS126 is an integrated circuit (IC) that belongs to the 74LS series of logic devices. Specifically, it is a Quad Bus Buffer Gate IC with 3-State Outputs. This IC contains four separate buffer gates, each with 3-state outputs, making it a versatile component for digital electronics applications where signal buffering and control are required.

Key Features:

Number of Buffer Gates: The 74LS126 IC integrates four individual buffer gates within a single package, allowing multiple signals to be buffered in a compact design.

3-State Outputs: Each buffer gate has 3-state outputs, which means it can be in one of three states: high (1), low (0), or high impedance (disconnected), allowing for effective signal control and isolation.

Input and Output Pins: The IC features separate input and output pins for each gate, making it easy to buffer digital signals.

Compatibility: The 74LS126 IC is part of the TTL (Transistor-Transistor Logic) family, ensuring compatibility with other TTL logic devices.

Wide Voltage Range: Typically, this IC operates over a broad voltage range, making it compatible with various supply voltages, such as 5V.

DIP Package: The 74LS126 IC is commonly available in a Dual Inline Package (DIP), which simplifies its use in breadboards and on PCBs (Printed Circuit Boards).


Signal Buffering: Used to buffer digital signals, ensuring that the input signal is faithfully reproduced at the output and capable of driving multiple loads.

Bus Control: Applied in bus control applications, allowing signals to be placed in a high impedance state to prevent conflicts or contention on a shared data bus.

Signal Isolation: Utilized for signal isolation, enabling signals to be separated and isolated when needed.

Digital Systems Interface: Connected to various parts of digital systems for signal buffering, ensuring reliable data communication.

System Control Logic: Integrated into control logic for systems where data signals need to be effectively controlled and managed.

Interfacing with External Devices: Used to interface with external devices and systems where signal compatibility and control are important.

The 74LS126 Quad Bus Buffer Gates with 3-State Outputs is a versatile component in digital electronics. Its ability to buffer signals and control their state, including a high impedance state, makes it valuable for a wide range of applications, from signal buffering to bus control and interfacing with external devices.
