MC74AC540, MC74ACT540, MC74AC541, MC74ACT541 Octal Buffer/Line Driver with 3-State Outputs
MC74AC540/74ACT540 MC74AC541/74ACT541 octal buffer/line drivers designed employed memory address drivers, clock drivers oriented transmitter/receivers. MC74AC541/74ACT541 noninverting option MC74AC540/74ACT540. These devices similar function MC74AC240/74ACT240 MC74AC244/74ACT244 while providing flow-through architecture (inputs opposite side from outputs). This pinout arrangement makes these devices especially useful output ports microprocessors, allowing ease layout greater board density.
