The driver outputs and the receiver inputs connect  
internally to form a differential input/output (I/O) bus port  
that is designed to offer minimum loading to the bus.  
This port operates over a wide range of common-mode  
voltage, making the device suitable for party-line  
applications. The device also includes additional  
features for party-line data buses in electrically noisy  
environment applications such as industrial process  
control or power inverters.

Meets or Exceeds the Requirements of ANSI  
Standard TIA/EIA-485-A and ISO 8482: 1987(E)  
The SN75LBC182 and SN65LBC182 bus pins also  
exhibit a high input resistance equivalent to one-fourth  
unit load allowing connection of up to 128 similar  
devices on the bus. The high ESD tolerance protects  
the device for cabled connections. (For an even higher  
level of protection, see the SN65/75LBC184, literature  
number SLLS236.)

The

design  
incorporates  
slew-rate-controlled outputs sufficient to transmit data  
up to 250 kbps. Slew-rate control allows longer  
unterminated cable runs and longer stub lengths from  
the main backbone than possible with uncontrolled  
voltage transitions. The receiver design provides a  
fail-safe output of a high level when the inputs are left  
floating (open circuit). Very low device supply current  
can be achieved by disabling the driver and the receiver.

The SN65LBC182 is characterized for operation from  
−40°C to 85°C, and the SN75LBC182 is characterized  
for operation from 0°C to 70°C.  
DESCRIPTION  
The SN65LBC182 and SN75LBC182 are differential  
data line transceivers with a high level of ESD protection  
in the trade-standard footprint of the SN75176. They are  
designed for balanced transmission lines and meet  
ANSI standard TIA/EIA-485-A and ISO 8482. The  
SN65LBC182 and SN75LBC182 combine a 3-state,  
differential line driver and differential input line receiver,  
both of which operate from a single 5-V power supply.  
The driver and receiver have active-high and active-low  
enables, respectively, which can be externally  
connected together to function as a direction control.
