Octal Buffer/Line Driver

with 3ĆState 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.

• 3-State Outputs

• Inputs and Outputs Opposite Side of Package, Allowing

Easier Interface to Microprocessors

• Outputs Source/Sink 24 mA

• MC74AC540/74ACT540 Provides Inverted Outputs

• MC74AC541/74ACT541 Provides Noninverted Outputs

• ′ACT540 and ′ACT541 Have TTL Compatible Inputs
