T&R/T = Tape and reel Straight leads. #Denotes a RoHS-compliant device that may include lead that is exempt under the RoHS requirements. DESCRIPTION The DS2401 enhanced silicon serial number is a low-cost, electronic registration number that provides an absolutely unique identity which can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller) ...

... After one complete pass, the bus master knows the contents of the ROM in one device. The remaining number of devices and their ROM codes may be identified by additional passes. Refer to Application Note 187: 1-Wire Search Algorithm for a comprehensive discussion of a ROM search, including an actual example. iButton is a registered trademark of Maxim Integrated Products, Inc ...
