FEATURES  
DESCRIPTIO  
The LTC®491 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.

Designed for RS485 or RS422 Applications  
■
Single 5V Supply  
–7V to 12V Bus Common Mode Range  
Permits ±7V Ground Difference Between Devices

Live Insertion or Removal of Package  
Driver Maintains High Impedance in Three-State or  
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 SN75180

overload or ESD damage.  
■
■
The driver and receiver feature three-state outputs, with  
the driver outputs maintaining high impedance over the  
entire common mode range. 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.

Both AC and DC specifications are guaranteed from 0°C to  
70°C and 4.75V to 5.25V supply voltage range.
