Working Principles

The 74AHC125BQ-Q100,11 is a quad non-inverting buffer IC that amplifies and buffers digital signals. It features Schmitt-trigger inputs, which help improve noise immunity by providing hysteresis. The 3-state outputs allow the buffers to be disabled, effectively disconnecting them from the output bus.

When the Output Enable (OE) input is low, the outputs are enabled and mirror the corresponding inputs. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.

The IC operates using high-speed CMOS technology, which provides fast switching times and low power consumption.
