DESCRIPTION/ORDERING INFORMATION
These 16-bit buffers/drivers are designed specifically for low-voltage (3.3-V) VCC operation, but with the
capability to provide a TTL interface to a 5-V system environment.
The 'LVTH16240 devices are designed specifically to improve both the performance and density of 3-state
memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
