Please log in for more thread options TTL chip made by Texas Instruments: SN74118. A web search indicates it's some type of RS latch, but for testing purposes the pinout would really help. Thanks!!! Matt J. McCullar Arlington, TX | |||||||||||||||||||

Please log in for more thread options Are you certain of the number? I find no reference to a 74118 in my 1981 Texas Instruments TTL databook. (I'll check at work tomorrow - I have a somewhat newer TI book there...) -- Peter Bennett, VE7CEI peterbb4 (at) interchange.ubc.ca new newsgroup users info : http://vancouver-webpages.com/nnq GPS and NMEA info: http://vancouver-webpages.com/peter Vancouver Power Squadron: http://vancouver.powersquadron.ca | |||||||||||||||||||
