SN74LS541
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.
• Hysteresis at Inputs to Improve Noise Margin
• PNP Inputs Reduce Loading
• 3-State Outputs Drive Bus Lines
• Inputs and Outputs Opposite Side of Package, Allowing Easier
Interface to Microprocessors
• Input Clamp Diodes Limit High-Speed Termination Effects
