I'm looking for an equivalent to the venerable TPIC6C595 shift register/driver that could be driven by a micro running from 3.3V without having to add a level converter. Has anyone used or found such an animal? TIA, RR -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
