Bus Hold Circuitry to Retain Last Active State During Tri-State鈩?/div>
Available in SSOP and TSSOP Packages
Description
Atmel鈥檚 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 combination of ultra high
speed and low noise is the next step in high speed performance.
