FEATURES  
DESCRIPTIO  
The LTC®490 is a low power differential bus/line trans-  
ceiverdesignedformultipointdatatransmissionstandard  
RS485 applications with extended common mode range  
(12V to –7V). It also meets the requirements of RS422.  
Low Power: ICC = 300µA Typical  
Designed for RS485 or RS422 Applications  
Single 5V Supply  
7V to 12V Bus Common Mode Range  
Permits ±7V Ground Difference Between Devices

on the Bus  
Thermal Shutdown Protection  
Power-Up/-Down Glitch-Free Driver Outputs Permit  
Live Insertion or Removal of Package  
Driver Maintains High Impedance with the  
Power Off  
Combined Impedance of a Driver Output and  
Receiver Allows up to 32 Transceivers on the Bus  
70mV Typical Input Hysteresis  
28ns Typical Driver Propagation Delays with  
5ns Skew for 2.5MB Operation  
Pin Compatible with the SN75179  
Excessive power dissipation caused by bus contention or  
faults is prevented by a thermal shutdown circuit which  
forces the driver outputs into a high impedance state. The  
receiver has a fail safe feature which guarantees a high  
output state when the inputs are left open.  
Both AC and DC specifications are guaranteed from 0°C to  
70°C and 4.75V to 5.25V supply voltage range.
