Working Principles

The 74HC125PW-Q100J is a quad non-inverting buffer/line driver integrated circuit. It is designed to provide high-speed signal buffering and logic level shifting capabilities. The device operates with a supply voltage range of 2V to 6V, making it suitable for various digital systems.

The inputs (A1, A2, A3) are compatible with a wide range of logic levels, from GND to VCC. The outputs (Y1, Y2, Y3, Y4) are non-inverting and can drive signals within the same voltage range. The tri-state output control (OE#) allows the outputs to be disabled, effectively disconnecting them from the bus, which is useful for bus-oriented applications.

The 74HC125PW-Q100J provides efficient data transfer and logic level shifting between different voltage domains. It is commonly used in microcontroller-based systems, communication interfaces, and other digital applications where signal buffering and level shifting are required.
