MC74ACT540: Octal Buffer/Line Driver with 3-State Outputs
For complete documentation, see the data sheet
Product Description
The MC74AC540/74ACT540 and MC74AC541/74ACT541 are octal buffer/line drivers designed to be employed as memory and
address drivers, clock drivers and bus oriented transmitter/receivers. 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.
