description

The SN65LBC180 and SN75LBC180 differential
driver and receiver pairs are monolithic integrated
circuits designed for bidirectional data
communication over long cables that take on the
characteristics of transmission lines. They are
balanced, or differential, voltage mode devices
that meet or exceed the requirements of industry
standards ANSI RS-485 and ISO 8482:1987(E).
Both devices are designed using TI’s proprietary
LinBiCMOS with the low power consumption of
CMOS and the precision and robustness of
bipolar transistors in the same circuit.

Both the SN65LBC180 and SN75LBC180
combine a differential line driver and receiver with
3-state outputs and operate from a single 5-V
supply. The driver and receiver have active-high
and active-low enables, respectively, which can
be externally connected to function as a direction
control. The driver differential outputs and the
receiver differential inputs are connected to
separate terminals for full-duplex operation and
are designed to present minimum loading to the
bus whether disabled or powered off (V

These parts feature a wide common-mode
voltage range making them suitable for
point-to-point or multipoint data-bus applications.

description (continued)

The devices also provide positive and negative output-current limiting and thermal shutdown for protection from
line fault conditions. The line driver shuts down at a junction temperature of approximately 172°C.

The SN65LBC180 and SN75LBC180 are available in the 14-pin dual-in-line and small-outline packages. The
SN75LBC180 is characterized for operation over the commercial temperature range of 0°C to 70°C. The
SN65LBC180 is characterized over the industrial temperature range of –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values are with respect to GND.

2. The maximum operating junction temperature is internally limited. Use the dissipation rating table to operate below this temperature.
