Logic gates and circuits are a type of electronic device that is used to process and execute binary operations in a digital system. They are essentially composed of logic elements such as transistors, logic gates, and buffers. SN74HC126N is a high-speed quad-line receiver, one of the many logic-level elements. It is commonly used as a gate, buffer, or as an interface between elements. In this article, we will discuss the application field and working principle of the SN74HC126N.

Application Field of SN74HC126N

The SN74HC126N is mainly used in developing digital logic circuits such as logic gates, buffers and other logic devices. Most often, this device is used as a logic gate in digital logic designs. It can also be used to buffer the signal from one logic element to another, for example, for logic level conversion. Moreover, it can be used to interface a microcontroller to discrete logic elements and peripheral devices, such as serial data communications.

Working Principles of SN74HC126N

The SN74HC126N is a high-speed quad-line receiver, and is composed of four independent gates, each of which consists of four logic inputs-A,B,C and D, and two logic outputs-Y1 and Y2. The SN74HC126N works in the following way: when an input is applied to the logic input, it will be transmitted to two outputs simultaneously. The four inputs can be classified into two subgroups-A and B, and C and D. For A and B, when either one is high, the output is high and when both are low, the output is low. For C and D, both have to be high for the output to be high. If either one is low, the output is low.

The SN74HC126N also has an active LOW enable pin that can be used to disable all outputs of the device. When this is connected to a LOW level signal, the outputs of the SN74HC126N will be disabled, regardless of the input signals.

In summary, the SN74HC126N is a high-speed quad-line receiver which can be used to develop digital logic circuits like logic gates and buffers. It consists of four logic elements and has two output lines per element. The device has an active LOW enable pin, which can be used to disable all outputs. It can be used to interface microcontrollers with other discrete logic elements and peripheral devices.
