MC74ACT541
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
