Description
Atmel’s new family of high speed CMOS transceivers offers the best of all worlds to the user requiring stability and ultra fast speeds. These transceivers, which can function as two 8-bit devices or one 16-bit device, are capable of improving processing efficiency as much as 6% by reducing the number of wait states required during memory access. In addition, this family of parts has been designed to minimize ground bounce on the outputs while rejecting input spikes of up to 1.8V and 1 ns wide. This bination of ultra high speed and low noise is the next step in high speed performance.
