The N74F125D,623 is a single-gate logic quad buffer/line driver with two independent two-way direction control outputs. It is a member of the F125 family of buffers and is ideal for driving LED displays and other applications in which the outputs must be controlled by a single gate. The N74F125D, 623 operates from a single supply of 1.8V to 5.5V, so it is versatile and compatible with logic family from 5.0V CMOS to 3.3V, 2.5V and 1.8V. The N74F125D, 623 has fast switching speeds and low operating currents, making it suitable for a variety of applications.

Features of the N74F125D,623 include symmetrical sources, allowing faster switching times than many other buffers; low quiescent current of 0.75mA, ensures the device is more efficient; and the integrated two-way direction control outputs which can switch each output direction in opposite directions independently.

The N74F125D,623 is mainly used in low voltage logic buffer applications, such as LED displays, 7-segment LED displays, logic translation, data transmission and reception, and multichannel level translation.

The N74F125D,623 follows an open collector architecture, which makes it a bridge between one input control signal to two independent two-way direction control outputs. It has a protection chip built-in to prevent inrush current from damaging or overloading the logic downstream. It has a symmetrical transistor structure which allows for faster switching time.

The working principle of the N74F125D,623 is to provide a level translation from one input control signal to two individual two-way direction control outputs. It acts as a bridge between one primary control signal and two independent two-way control outputs. When the primary control signal is given, it is translated into two directions control signals, one being driven in the normal direction while the other drives in the opposite direction. Depending on the logic level of the input control signal, the effect is either to drive the two outputs before the primary output can be driven or to prevent the two outputs before the primary output can be driven.

The N74F125D,623 is an ideal buffer choice because of its fast switching speeds, low quiescent current and integrated two-way direction control output. The N74F125D, 623 is very versatile as it is compatible with logic families from 5.0V CMOS to 3.3V, 2.5V and 1.8V, making it suitable for a variety of applications such as level translation, logic buffers, and data transmission and reception.
