Logic circuits are essential components of any digital circuit. One of the most important logic components is the 74HCT126D,653, a high-speed logic buffer capable of providing logic conversion and data buffering. In this article, we will discuss its application fields and working principles.

Introduction to 74HCT126D,653

The 74HCT126D,653 is a high-speed 4-input logic buffer from Texas Instruments (TI). It is a logic component that is used to convert and buffer signals from one logic level to another. The 74HCT126D,653 is part of the High Speed CMOS (HSCMOS) family of devices from TI, which offer higher speed and lower power consumption than other standard logic components.

The 74HCT126D,653 is available in a range of packages including VSSOP (Voltage Source Small Outline Package), SSOP (Shrink Small Outline Package), SOIC (Small Outline Integrated Circuit), and many more. It operates at a wide supply voltage range between 2.5V and 5.5V.

Application Fields of 74HCT126D,653

The high speed operation of the 74HCT126D,653 makes it an ideal component for high speed data buffering and logic conversion applications. The device is used in digital circuits that require fast switching of digital inputs and outputs, such as bus signal processing. It is also suitable for a variety of digital signal processing applications such as signal conditioning, logic gate implementations, data transmission, and digital control. The high switching speed makes it ideal for applications where high data rates are required.

The 74HCT126D,653 is also used in digital integrated circuits, such as microcontrollers, FPGAs (Field Programmable Gate Arrays), and ASICs (Application Specific Integrated Circuits). The device can be used as an input or output buffer in these applications, providing logic translation and high speed data buffering.

Working Principle of 74HCT126D,653

The 74HCT126D,653 is a 4-input, 2-bit multiplexer. The device consists of four control inputs and two data inputs, corresponding to the four data channels, and the two output channels. The 4-input control inputs determine which of the input data sources is connected to the output channel. The device can be used as either a 2-to-1 multiplexer, connecting any one of the four data sources to one output, or as a 2-to-4 data demultiplexer, allowing for two channels of data to be connected to four outputs.

The device also includes a 3-state buffer, which can be used to place the outputs in a high impedance state. This allows for multiple devices to be connected together in a shared bus configuration, as the outputs of one device do not interfere with the inputs of the other. The device also features high speed switching operations, with a maximum output propagation delay of only 10ns.

Conclusion

The 74HCT126D,653 is a high-speed 4-input logic buffer from Texas Instruments, capable of providing high speed data conversion and buffering. It is suitable for a variety of applications, including digital signal processing, logic gate implementations, data transmission, and digital control. The device is also suitable for applications that require high speed switching, as it can operate at a maximum output propagation delay of only 10ns. The device is available in a range of packages and operates over a wide supply voltage range.
