PL IA NT Features CO M ■ *R oH S ■ ■ ■ ■ Lead free RoHS compliant* Multiple resistors tied to a common node Stable thin-film-on-silicon technology Ultra-miniature packages to JEDEC standards Applications ■ ■ ■ Bus termination Pull-up/pull-down Ideal for space-constrained applications Thin Film on Silicon 2QSP / 2NBS-XX2 Bussed Resistors General Information Package Schematic Bussed Resistor networks are typically used in DC pull-up and pull-down applications where system data or control lines must be tied to a fixed potential. Fabricated with a Tantalum Nitride and Nickel Chromium on Silicon process, these resistors feature excellent stability, TCR and tracking performance. Bussed Resistor Networks are available in a range of miniature package types conforming to JEDEC standards. 16 15 14 13 12 E T E L O S B O 1 2 3 4 5 11 10 9 6 7 8 Electrical & Environmental Characteristics Electrical Characteristics Resistance Range Tolerance: Absolute Ratio TCR: Absolute Tracking Operating Voltage Symbol Minimum Maximum Unit R 100 Nominal 100 K Ω ±0.5 % ±0.1 % ±5 % ±2 % Ω Ω 150 25 50 ppm/°C ppm/°C V +125 +150 0.1 V °C °C Watt 0.75 1.00 1.12 Watt Watt Watt 0.60 1.00 Watt Watt 100 Environmental Characteristics ESD Operating Temperature Storage Temperature Power Rating per Resistor @ 70 °C Power Rating per Package @ 70 °C: QSOP: 16 Pin 20, 24 Pin 28 Pin TJ Tstg NBSOIC: 8 Pin 14, 16 Pin *RoHS Directive 2002/95/EC Jan 27, 2003 including Annex Specifications are subject to change without notice.
