description
The ’LVTH162240 devices are 16-bit buffers/drivers designed specifically for low-voltage (3.3-V) V
CC
operation
and to improve both the performance and density of 3-state memory address drivers, clock drivers, and
bus-oriented receivers and transmitters. They have the capability to provide a TTL interface to a 5-V system
environment.
These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer and provide inverting
outputs and symmetrical active-low output-enable (OE) inputs.
The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-Ω series resistors to
reduce overshoot and undershoot.
