General Information

The Model 2DTA Series High Performance Memory Bus

Terminator is well-suited for high speed bus termination

applications where variable bus loading and very low

terminator power dissipation are required. This very efficient

high speed terminator array is highly integrated and is very

effective for use in space constrained applications such as PC

notebooks and motherboards, engineering workstations and

portable battery powered devices. Two performance options

are available. The higher grade 2DTA-5 with a maximum

forward voltage of 0.75 V is suited for ultra-fast and dense

memory termination configurations. The 2DTA-10, with a

maximum specified forward voltage of 0.85 V is primarily

targeted to general purpose applications where board space is

critical.
