Octal Buffer/Line Driver

with 3−State Outputs

The SN74LS541 is an octal buffer and line driver with the same

functions as the LS241, but with pinouts on the opposite side of the

package.

This device type is designed to be used as a memory address driver,

clock driver and bus-oriented transmitter/receiver. This device is

especially useful as output ports for the microprocessors, allowing

ease of layout and greater PC board density.
