1 QP October 29, 03 QP Quad High Speed Differential Line Driver Quad Differential Line Receiver (0mv input seitivity over ± 7V input range) Quad Differential Line Receiver (500mv input seitivity over ± 15V input range) General Description The QP26LSxx family of interface products were re-engineered in a modern wafer fabrication process to replace AMD 26LSxx devices. All features of the AMD devices were duplicated; the devices are plug and play compatible. The circuit design and wafer fab process selected duplicates the electrical characteristics of the original devices, including parasitic performance. Failsafe characteristics were duplicated for the line receivers. The QP26LSxx family is designed to meet the requirements of RS-4, RS-423, Federal Standards 10 and 10 for balanced and unbalanced digital data tramission. The QP is designed to provide unipolar differential drive to twisted-pair or parallel-wire tramission lines. The device provides both enable and disable functio common to all four drivers. It features tri-state outputs and logical OR-ed complementary enable inputs. The inputs are all LS compatible and are all one unit load. The features an input seitivity of 0mV over the input voltage range of ±7V while the features an input seitivity of 500mV over the input voltage range of ±15V. Both provide and enable and disable function common to all four receivers. Both feature tri-state outputs with 8mA sink capability and incorporate a fail-safe inputoutput relatiohip that keeps the outputs high when the inputs are open. The family is cotructed using Advanced Low-Power Schottky processing. Block Diagrams QP 29 Oakmead Village Ct, Santa Clara, CA Phone: (408) Fax: (408) Internet:
