MC74AC540 Overview
The MC74AC541/74ACT541 is a noninverting option of the MC74AC540/74ACT540. These devices are similar in function to the MC74AC240/74ACT240 and MC74AC244/74ACT244 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density.
