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.
Note:
1. The function shown is repeated 3 additional times on each device.
