The M74HC126B1R is a popular logic device in various consumer, industrial, and commercial applications. It is a 12-bit, 3-state buffering IC designed to buffer signals in either direction and provide various levels of buffering, loading, and hysteresis. The chip is designed to convert digital voltages to analog outputs. Because of its versatility and its low power consumption, the M74HC126B1R is a favorite among manufacturers and designers.

The M74HC126B1R belongs in the Logic – Buffers, Drivers, Receivers, Transceivers category. Inside the device, there are 12 buffers which contain 2 NAND gates and 2 inverters. The first two NAND gates are conventional two-input NAND gates and the second pair provides the choice of driving either direction. The first two inverters are the buffers for the second two NAND gates. The third inverter is the pull-down network providing the buffer for the input signal.

The M74HC126B1R is designed to drive both CMOS and TTL logic circuits, while providing maximum protection against static charge buildup and EMI interference. The device also has an active high output enable pin that can be used to control the input/output operation. Its operating voltage range is 4.5V to 7.5V and the supply current is just 3µA max.

Working principle wise, the M74HC126B1R operates in one of two modes. In the ‘Z’ mode, the input and output will be tristate and the output will high-impedance. The second mode is the ‘X’ mode which will drive the output to a logic level 0 or 1. Also, the device has two additional pins which can be used to control the direction of the flow of data. The number of bits used for a given application depends upon the control signals used to select the direction of the flow.

The M74HC126B1R is extremely useful in many consumer, industrial, and commercial applications. For example, it is used in DSPs, memory controllers, LCD displays, and other types of display drivers. In addition, it is also used for signal conditioning and signal buffering, as well as in communications systems and networks. The M74HC126B1R can be used in anywhere that signal buffering and signal splitting is required.

In summary, the M74HC126B1R is a useful logic device. It belongs in the Logic – Buffers, Drivers, Receivers, Transceivers category. It is designed to drive both CMOS and TTL logic circuits and comes with two additional pins which can be used to control the direction of the flow of data. It is used in many consumer, industrial, and commercial applications, and is perfect for signal buffering and signal splitting. Overall, the M74HC126B1R is an ideal choice for any buffering or switching application.
