Description

Atmel’s Fast Logic 16-Bit Buffer/Line driver provides bus interface and signal buffering at the fastest speeds available in the industry. The Tri-state outputs can be set for either 4-bit, 8-bit, or 16-bit independent operation. The AT16244 also has bus-hold circuitry which retains the last state of the input whenever a high impedance level is detected, and eliminates the need for pull-up or pull-down resistors. Minimal ground bounce and high input noise rejection make this device excellent for use in all high speed interface applications.
