DESCRIPTION

The SP3070-3078E differential line transceivers are suitable for bidirectional communication

on balanced multipoint bus transmission lines and comply with both RS485 and RS422 EIA

Standards. Each device consists of a differential driver and differential receiver. All devices

operate from a 3.3V power supply.

High receiver input impedance allows a large number of transceivers to share a common data

bus while maintaining signal margin and without excessive loading or use of expensive

repeaters. The high impedance driver output is maintained over the entire common-mode

voltage range from -7 to +12V. Receivers will failsafe to logic 1 output when inputs are open,

shorted or terminated. Drivers include built-in short-circuit protection and a thermal-overload

shutdown to protect against excessive power dissipation from bus contention or cable faults.

All RS485 inputs are ESD protected up to ±15kV (Air-Gap and Human Body Model) and up

to ±8kV Contact discharge (IEC 1000-4-2).
