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.
