The device meets the requirementsof TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller andthe serial-port connector. The charge pump and four small external capacitors allow operation from a single 5-Vsupply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/μs driver outputslew rate.(1)ORDERING INFORMATION(2)T PACKAGE ORDERABLE PART NUMBER TOP-SIDE MARKINGATube of 25 MAX208CDWSOIC – DW MAX208CReel of 2000 MAX208CDWR0°C to 70°CTube of 60 MAX208CDBSSOP – DB MA208CReel of 2000 MAX208CDBRTube of 25 MAX208IDWSOIC – DW MAX208IReel of 2000 MAX208IDWR–40°C to 85°CTube of 60 MAX208IDBSSOP – DB MB208IReel of 2000 MAX208IDBR(1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TIweb site at |
