74LS540规格书详情
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
