SP481R/SP485R  
1/10th Unit Load RS-485Transceiver  
FEATURES  
Allows Over 400 Transceivers On A  
Transmission Line (1/10th Unit Load)  
High Impedance on Receiver Inputs  
(RIN = 150ktypical)  
Half-Duplex Configuration Consistent  
With Industry Standard Pinout  
–7V to +12V Common Mode Input  
Voltage Range  
Includes Shutdown Mode (ICC < 10µA)  
(For SP481R Only)  
Low Power Consumption (250mW)  
Separate Driver and Receiver Enable  
Now Available in Lead Free Packaging  
DESCRIPTION  
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  
or8-pinnarrowSOICpackage. The SP481Roffersashutdownfeatureviatheenablepinswhich  
will reduce the supply current (ICC) below 0.5µA typical.
