These devices are pin-to-pin compatible with popular industry standards. As with the initial versions, the SP232A/233A/310A/312A devices feature at least 120Kbps data rate under load, 0.1µF charge pump capacitors, and overall ruggedness for commercial applications. This family also features Sipex's BiCMOS design allowing low power operation without sacrificing performance. The series is available in plastic DIP and SOIC packages operating over the commercial and industrial temperature ranges.Now Available in Lead Free PackagingVCCGND T1OUT R1INR1OUT T1INT2INR2OUTC1+V+ C1-C2+C2-V-T2OUTR2INSP232A12345678161514131211109FEATURES2Jan 31-07 Rev B SP232A/233A/310A/312A © 2007 Sipex CorporationThis is a stress rating only and functional operation of the device atthese or any other conditions above those indicated in the operationsections of this specification is not implied.
