74LVC1G125DBVRG4 is a single 1-bit non-inverting buffer/line driver with 3-state output designed for general-purpose flip-flop, clock and data buffer applications. This type of device belongs to the logic family, including buffers, drivers, receivers, and transceivers.

Application Field

74LVC1G125DBVRG4 is designed to address the demanding design needs in a wide range of applications. Ideal applications include high speed data transmission in applications such as video or audio processing and processing of network signals, high speed buffering of address and data lines, memory interfaces, microprocessor systems, 3V to 5V bus interface and small scale I/O buffers.

This device includes an enable (EN) input to independently control output state. When EN is high, the outputs of buffers are disabled, forcing the logic state of the outputs to the high-impedance (OFF) state. This device is available in standard or green packages, the Green packages have restriction on hazardous substances (RoHS compatible).

Working Principle

This buffer exhibits several practical characteristics that make it ideal for data transmission systems. Its tiny SOIC 8 package average power dissipation is as low as 0.1W, ensuring high efficiency operation and its high frequency transmission of more than 250MHz eliminates any potential issues of signal integrity.

The 74LVC1G125DBVRG4 buffer is a non-inverting standard buffer featuring two input lines, two output lines, and a single enable input. The two input lines are: IN, the input pin that receives data from the source, and EN, the enable pin that determines whether or not the buffer will accept and transmit the data from the source. The two output lines are: OUT, the output pin that transmits output data to the sink, and Q, the feedback pin that sends any output data to the buffer’s input.

When EN is low, the outputs are enabled and any change in the logic level of the input will be transmitted to the output in the same logic level. When EN is high, the outputs of the buffer are disabled, forcing the logic state of the output to the high-impedance (OFF) state. This enables the buffer to be quickly turned off, thus preventing unintended data transmission.

The 74LVC1G125DBVRG4 buffer is also designed to work like a level translator, providing an output compatible with the voltage applied to its VCC pin, while receiving an input signal whose voltage is different. This allows it to be used in both 3.3V and 5V systems and ensures that it is compatible with a wide range of input and output logic levels.

The 74LVC1G125DBVRG4 buffer is commonly used in various applications such as digital video processing, transmitting high-speed digital signals, buffering address and data lines, microprocessor systems, and amplifying low-voltage signals. Its low power consumption and high transmission speed make it suitable for all types of digital designs.
