74AC541, 74ACT541
Octal Buffer/Line Driver with 3-STATE Outputs
Features
General Description
■ I and I reduced by 50%
The 74AC541 and 74ACT541 are octal buffer/line
drivers designed to be employed as memory and
address drivers, clock drivers and bus oriented transmitter/
receivers.

■ 3-STATE outputs
■ Inputs and outputs opposite side of package, allowing
easier interface to microprocessors
These devices are similar in function to the 74AC244
and 74ACTC244 while providing flow-through architec-
ture (inputs on opposite side from outputs). This pinout
arrangement makes these devices especially useful as
an output port for microprocessors, allowing ease of
layout and greater PC board density.
■ Output source/sink 24mA
■ 74AC541 is a non-inverting option of the 74AC540
■ 74ACT541 has TTL-compatible inputs
