Sipex Corp. announced a new family of nine 3V RS485 transceivers with very low power consumption and high ESD. All nine products in this family are fully compatible upgrades to standard RS485 and RS422 transceivers and include many advanced features making them ideal for use in industrial, telecom and consumer applications.

The Sipex family of interface ICs facilitate the transfer of digital signals between or within electronic systems and ensure reliable, wired connectivity between networks, computers and the rapidly expanding mix of digital peripherals and portable devices that connect to them. The serial interface product group contains RS-232, RS422, RS-485, USB and multiprotocol transceivers.

These transceivers feature extremely high input impedance and low input current. All devices have enhanced ESD protection up to 15kV (IEC1000-4-2 Air-gap test and Human Body Model). Typical power consumption in shutdown mode is 150nW. Six members of the family (SP3070E, SP3071E, SP3072E, SP3073E, SP3074E and SP3075E) have slew rate limited outputs for operation on long or uncontrolled data buses. Three devices (SP3076E, SP3077E and SP3078E) are designed for high speed signaling and support data rates up to 16Mbps.

Other advanced features include enhanced failsafe protection, internal current limit and automatic thermal shutdown. Control inputs are "hot-swap" protected and are internally held inactive to protect against false outputs during power transitions. Devices are available in commercial or industrial temperature ranges.

All devices are available now in PDIP and SOIC packaging. Pricing begins at $1.20 in 1,000-piece quantities.
