The SN75LBC771 is a low-power LinBiCMOS
device that incorporates the drivers and receivers
for a 9-pin GeoPort host interface. GeoPort
combines hybrid EIA/TIA-422-B and EIA/
TIA-423-B drivers and receivers to transmit data
up to four-Mbit/s full duplex. GeoPort is a serial
communications standard that is intended to
replace the RS-232, AppleTalk, and printer ports
all in one connector in addition to providing

capability.
The
SN75LBC771 provides point-to-point connec-
tions between GeoPort-compatible devices with
data transmission rates up to 4-Mbit/s full duplex
featuring a hot-plug capability. Applications
include connection to telephone, ISDN, digital
sound and imaging, fax-data modems, and other
traditional serial and parallel connections. The
GeoPort is backwardly compatible to both
LocalTalk and AppleTalk.

WhiletheSN75LBC771ispoweredoff(V andV =0),theoutputsareinahigh-impedancestate.Also,when
CC

the shutdown (SHDN) terminal is high, all outputs go into a high-impedance state. A logic high on the driver
enable (DEN) terminal places the outputs of the differential driver into a high-impedance state. All drivers and
receivers have fail-safe mechanisms that ensure a high output state when the inputs are left open.
The SN75LBC771 is characterized for operation over the 0°C to 70°C temperature range.

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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 network ground terminal unless otherwise noted.
2. This rating is per MIL-STD-883C, Method 3015.7.
