SP3070E - SP3078E Family Data Sheet 15kV ESD-Protected, 3.3V, 1/8 Load, Failsafe RS-485/RS-422 Transceivers General Description Features The SP3070E - SP3078E differential line transceivers are 15kV ESD protection for RS-485 pins suitable for bidirectional communication on balanced 3.3V low-power operation multi-point bus transmission lines and comply with both RS-485 and RS-422 EIA Standards. Each device consists Advanced receiver-failsafe protection for open, shorted of a differential driver and differential receiver. All devices or terminated lines operate from a 3.3V power supply. Up to 256 transceivers may share Bus High receiver input impedance allows a large number of Very low load for 8x greater fanout transceivers to share a common data bus while maintaining signal margin and without excessive loading Hot Swap glitch protection RE and DE or use of expensive repeaters. The high impedance driver Thermal shutdown protects against driver contention output is maintained over the entire common-mode Available in three industry standard footprints voltage range from -7 to +12V. Receivers will failsafe to logic 1 output when inputs are open, shorted or SP3070E, SP3073E and SP3076E in Full-Duplex terminated. Drivers include built-in short-circuit protection (14-pin) and a thermal-overload shutdown to protect against SP3071E, SP3074E and SP3077E in Full-Duplex excessive power dissipation from bus contention or cable (8-pin) faults. All RS-485 receiver inputs and driver outputs are SP3072E, SP3075E and SP3078E in Half-Duplex ESD protected up to 15kV (Air-Gap and Human Body (8-pin) Model) and up to 8kV Contact Discharge (IEC 61000-4- Three applications-optimized speed grades 2). The SP3070E - SP3078E devices may not achieve SP3070E - SP3072E: 250kbps slew-limited optimal transmit performance if the connected receiver includes a biasing network to 5.0V without a termination SP3073E - SP3075E: 500kbps slew-limited resistor.
