Interface Transceiver  
FEATURES  
DESCRIPTION  
The LTC®485 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.  
n
Low Power: I = 300μA Typ  
CC  
n
Designed for RS485 Interface Applications  
n
Single 5V Supply  
n
–7V to 12V Bus Common Mode Range Permits  
±7V ꢀround Difference Between Devices on the Bus  
The CMOS design offers significant power savings over  
its bipolar counterpart without sacrificing ruggedness  
against overload or ESD damage.  
n
Thermal Shutdown Protection  
n
Power-Up/Down ꢀlitch-Free Driver Outputs  
Permit Live Insertion or Removal of Transceiver  
n
The driver and receiver feature three-state outputs, with  
the driver outputs maintaining high impedance over the  
entire common mode range. Excessive power dissipa-  
tion caused by bus contention or faults is prevented by a  
thermal shutdown circuit which forces the driver outputs  
into a high impedance state.  
Driver Maintains High Impedance in Three-State  
or with the Power Off  
n
Combined Impedance of a Driver Output and  
Receiver Allows Up to 32 Transceivers on the Bus  
(C- and I-ꢀrades)  
n
70mV Typical Input Hysteresis  
n
30ns Typical Driver Propagation Delays  
The receiver has a fail-safe feature which guarantees a  
high output state when the inputs are left open.  
with 5ns Skew for Up to 2.5MB Operation  
n
Pin Compatible with ±±0V Protected LTC28±2  
The LTC485 is fully specified over the commercial and  
extended industrial temperature range.
