The MM74HC126N belongs to Logic - Buffers, Drivers, Receivers, Transceivers. It is a 4-bit buffer/line driver with 3-state outputs designed to drive data buses or other relatively high-impedance lines. This device consists of four independent non-inverting buffers. This device features an active-low reset input which makes the device useful in applications where logic levels may become unleveled or indeterminate. The output circuit can drive 15 TTL loads or larger. Its output impedance is relatively high and is designed to drive relatively long lines.

The MM74HC126N has a variety of application fields. These include:

• Data Bus Drivers
• Linear Interface Circuits
• Interface Between Logic Circuits

The working principle of MM74HC126N is relatively simple. This device is built using semiconductor technology, and its components are as follows: four independent non-inverting buffers with 3-state outputs, an active-low reset input, and a logic control unit. When the device receives an active-low reset input, it activates the logic control unit, which then controls the operation of the buffers by changing their output from 3-state to logic-level output.

The logic control unit is responsible for controlling the 3-state outputs of the buffers. The unit senses any active-low reset input and sets the output of the buffers to 3-state, disabling the outputs and preventing them from changing the logic levels of the output. Once an active-low reset signal has been processed, the logic control unit sets the buffers to logic-level output, allowing them to drive the output lines to their new logic levels.

Another aspect of MM74HC126N is its ability to drive fifteen TTL loads or larger. The output impedance of this device is relatively high and is designed for driving relatively long lines. This allows for it to be used in interface between logic circuits in applications such as data buses and linear interface circuits. It can also be used for other applications such as power line drivers.

In conclusion, the MM74HC126N is a frequently used logic device which belongs to Logic - Buffers, Drivers, Receivers, Transceivers. It consists of four independent non-inverting buffers with 3-state outputs, and an active-low reset input. The output circuit of this device can drive fifteen TTL loads or larger, and has relatively high output impedance which can be used to drive relatively long lines. It is commonly used for interface between logic circuits, data bus, and linear interface circuits.
