description/ordering information
These octal buffers/drivers are designed
specifically for low-voltage (3.3-V) V_CC operation,
but with the capability to provide a TTL interface
to a 5-V system environment.
The ’LVTH540 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.
