DESCRIPTION

The SP307XE family contains differential line transceivers suitable for high speed bidirectional

communication on multipoint bus transmission lines. They are designed for balanced data

transmission and comply with both RS485 and RS422 EIA Standards. Each part contains one

differential driver and one differential receiver. SP3071E, SP3073E, SP3074E, SP3076E, and

SP3077E are full-duplex devices. SP3072E, SP3075E, and SP3078E are half-duplex devices.

SP3070E, SP3073E, SP3076E, and all half-duplex devices allow enable and disable both driver

and receiver independently. The high impedance driver output is maintained over the entire

common-mode voltage range from -7 to +12V.

The SP307XE family operates from a single 3.3V power supply. Excessive power dissipation

caused by bus contention or by output shorting is prevented by short-circuit protection and

thermal shutdown. This feature forces the driver output into high-impedance state if, during fault

conditions, the absolute value of the output current exceeds 250mA or the junction temperature

exceeds 165ºC.

Up to 256 transceivers may be connected simultaneously on a bus, but only one driver should

be enabled at a time.

The receiver contains a fail-safe feature that results in a logic high state if the inputs are

unconnected (floating), shorted or terminated.

The SP30XXE family is fabricated on BICMOS technology. All inputs and outputs have ESD

protection. Bus pins are ESD protected up to ± 15kV from Air-Gap and Human Body Model

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