Working Principles

The SN74ALVC126PWR is a buffer/driver integrated circuit that provides voltage-level translation and signal buffering capabilities. It consists of four independent buffers with 3-state outputs, allowing bidirectional data flow. The input signals are amplified and level-shifted to match the desired logic levels, which can be either TTL or CMOS. The output enable (OE#) input controls the state of the outputs, enabling or disabling their functionality.
