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.
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
