Bus Transceiver  
FEATURES  
DESCRIPTION  
The LTC®1485 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.

28ns Typical Driver Propagation Delays  
with 4ns Skew  
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  
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  
60mV Typical Input Hysteresis

The CMOS with Schottky design offers significant power  
savings over its bipolar counterpart without sacrificing  
ruggedness against overload or ESD damage.  
n
n
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. I/O pins are protected against  
multiple ESD strikes of over 10kV.

n
Pin-Compatible with the SN75176A, DS75176A,  
and SN75LBC176  
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 –40°C  
to 85°C and 4.75V to 5.25V supply voltage range.
