The SN75LBC773 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  
SN75LBC773 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.

While the SN75LBC773 is powered off (V  
and V = 0), the outputs are in a high-impedance state. A logic  
EE  
CC  
high on the driver enable (DEN) or logic low on the receive enable (REN) terminals places the outputs of the  
differential driver and receivers, respectively, 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 SN75LBC773 is characterized for operation over the 0°C to 70°C temperature range.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.

Eco Plan  
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS  
&
no Sb/Br)  
-
please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.
