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.
Features
• 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
• Pb−Free Packages are Available
