General Information  
Package Schematic

Dual Terminator networks are used to correctly terminate  
single-ended SCSI bus lines. The standard R1, R2 combina-  
tion ensures that the high frequency component of a signal  
transition will see an impedance at the termination equal to  
the characteristic impedance of the line. Fabricated with  
Tantalum Nitride on Silicon, these resistors feature excellent  
stability, TCR and tracking performance. The JEDEC  
standard miniature packages offer the most space-efficient  
Dual Terminator resistor array available.
