Hi Gurus, Which is a better way between the two topologies to terminate a signal by a external pullup. Topology one. Connecting the Pullup from the receiver Pin as close as possible. ----------- Driver ------------>|Receiver |---Pullup--->Vcc |---------- Topology two The driver sees the Pullup first before connecting to the receiver. Vcc | | Driver ------------>Pullup----->Receiver I personally think topology one is a better choice since there is no stub being created in routing the pullup where as in topology II there is a stub from the Pullup to the receiver. I would really be thankful if you guys can share ur thoughts on this. thanks, Rahul. _____________________________________________________________ Get 25MB, POP3, Spam Filtering with LYCOS MAIL PLUS for $19.95/year. http://login.mail.lycos.com/brandPage.shtml?pageId=plus&ref=lmtplus ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
