74AC541, 74ACT541
Octal Buffer/Line Driver with 3-STATE Outputs
Features
■ ICC and IOZ reduced by 50%
■ 3-STATE outputs
■ Inputs and outputs opposite side of package, allowing
easier interface to microprocessors
■ Output source/sink 24mA
■ 74AC541 is a non-inverting option of the 74AC540
■ 74ACT541 has TTL-compatible inputs
General Description
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.
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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
