description/ordering information
The SN74LVT32240 is a 32-bit buffer and line driver designed for low-voltage (3.3-V) V_CC operation, but with
the capability to provide a TTL interface to a 5-V system environment. This device can be used as eight 4-bit
buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. The device provides inverted outputs and
symmetrical active-low output-enable (OE) inputs. It is designed specifically to improve both the performance
and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
