Second, a thermal-shutdown circuit, forces
the driver outputs into a high-impedance
state if the die temperature becomes ex-
cessive.
lINE lENGTH
The RS-485/RS422 standard covers line
lengths up to 4000ft.
TyPICal aPPlICaTIONS
The SP3072E, SP3075E and SP3078E
transceivers are designed for bidirectional
data communications on multipoint bus
transmission lines.
DETaIlED DESCRIPTION
To minimize reflections, terminate the line at
both ends in its characteristic impedance,
and keep stub lengths off the main line as
short as possible. The slew-rate-limited
SP3070E - SP3075E are more tolerant of
imperfect termination.
