The SP3070E - SP3078E family is a series of ±15kV ESD-protected, 3.3V, 1/8 load, failsafe RS-485/RS422 transceivers. It features high ESD protection, low power operation, advanced receiver failsafe protection, high load capacity, hot swap glitch protection, etc.
The document describes the Sipex SP3070-3078E family of differential line transceivers suitable for bidirectional communication on balanced multipoint bus transmission lines. These devices comply with both RS-485 and RS-422 EIA Standards and operate from a 3.3V power supply.
Key features include +15kV ESD protection, advanced receiver-failsafe protection for open or shorted lines, and the ability to support up to 256 transceivers sharing a bus. The family is available in three industry-standard architectures (Full-Duplex 14-pin, Full-Duplex 8-pin, Half-Duplex 8-pin) with optimized speed grades ranging from 250kbps to 16Mbps.
