Octal Buffer/Line Driver
with 3-State Outputs
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.
