OCTAL BUFFER/LINE DRIVER

WITH 3-STATE OUTPUTS

The SN54/74LS540 and SN54/74LS541 are octal buffers and line drivers

with the same functions as the LS240 and LS241, but with pinouts on the

opposite side of the package.

These device types are designed to be used as memory address drivers,

clock drivers and bus-oriented transmitters/receivers. These devices are

especially useful as output ports for the microprocessors, allowing ease of

layout and greater PC board density.

WITH 3-STATE OUTPUTS

LOW POWER SCHOTTKY

• 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
