DESCRIPTION/ORDERING INFORMATION
The SN54LVC540A octal buffer/driver is designed for
2.7-V to 3.6-V V_CC operation, and the SN74LVC540A
octal buffer/driver is designed for 1.65-V to 3.6-V V_CC
operation.
These devices are ideal for driving bus lines or buffer
memory address registers. These devices feature
inputs and outputs on opposite sides of the package
that facilitate printed circuit board layout.
