DN7 diode terminator network This diode network is designed to provide eighteen channels for active termination of high-speed data signals to eliminate signal undershoot and overshoot. The network has the added benefit of acting to suppress any ESD voltage events by shunting the energy to ground assuring maximum reliability of electronic systems in the field. Trigger levels are defined by the positive and negative bias levels set by the user. features Negligible reverse recovery time Low capacitance Low forward voltage drop 18-channel terminator in a single package Resolved bus impedance mismatch applications Termination of data/control signals 66 MHz Dynamic RAM bus termination RISC architecture dimensions and construction Dimensions inches (mm) Size Code L W p L .341 .150 .033 Bonding Q24 (8.66) (3.81) (0.84) Wire p Lead W Die Pad Si Wafer Molded Resin ordering information New Part DN7 Q24 L TEB Package Termination Type Packaging Symbol Material Package type symbol + number of pins L: SnPb TEB: 13 embossed plastic tape QSOP: Q24 For further information on packaging, please refer to Appendix C.
