| oH V SC AV ER OM AI SIO PL LA N IA BL S NT E Features 24Q DTA 2 005 041 Lead free versions available RoHS compliant (lead free version)* 18 termination channels Incorporates 36 bi-directional Schottkybased diodes Small form factor replaces 18 SOT23 packages Low forward voltage (2 options available) Very fast recovery time *R Thin Film on Silicon 2DTA High Performance Memory Bus Terminator General Information Package Schematic 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.
