The SN74AHCT126PWR is a quad bus line driver with Tri-State buffers manufactured by Texas Instruments. It features a wide voltage operation range from 2V to 6V, and offers four –3-state non-inverting (high-impedance) outputs. The device also incorporates a Schmitt-trigger input stage which provides hysteresis for improved noise immunity. It can handle a wide variety of input and output types, and its outputs are capable of driving 10 loads, allowing for external signal buffering. Furthermore, the SN74AHCT126PWR is rated for 500V ESD protection, making it suitable for a range of industrial and consumer applications, such as automotive, avionics, and data processing. It is also a power-saving device, with a supply current of 4mA, making it an affordable and energy-efficient choice.
