■
Allows Over 400 Transceivers On A
Transmission Line (1/10th Unit Load)
■
High Impedance on Receiver Inputs
(R

typical)
■
Half-Duplex Configuration Consistent
With Industry Standard Pinout
■
–7V to +12V Common Mode Input
Voltage Range
■
Includes Shutdown Mode (I
CC
< 10

(For SP481R Only)
■
Low Power Consumption (250mW)
■
Separate Driver and Receiver Enable
The
SP481R
and
SP485R
are pin-to-pin equivalent with our existing SP485 product and contain
enhancements such as higher ESD tolerance and high receiver input impedance. The higher
receiver input impedance allows for connecting over 400 transceivers on a single transmission
line without degrading the RS-485 driver signal. Each device is packaged in an 8-pin plastic DIP
or 8-pin narrow SOIC package. The
SP481R
offers a shutdown feature via the enable pins which
will reduce the supply current (I
CC
) below 0.5
μ
A typical.
