Texas Instruments (TI) announced the ISO1176T isolated half-duplex differential line transceiver with integrated transformer driver. The TI ISO1176T provides the primary voltage for an isolation transformer. The ISO1176T offers the smallest isolated signal and power system design with highest efficiency and lowest electromagnetic interference (EMI). The 16-pin SOIC ISO1176T is available now for $3.30 (in quantities of 1,000). Two other isolated full-duplex RS-485 transceivers with transformer drivers, one operating at 5 V and other operating at 3.3 V, will be available by the end of this quarter.
