GeoPort Peripheral (DCE) Interface Device  
LinBiCMOS Process Technology  
description  
The SN75LBC776 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 megabits per second (Mbit/s) full duplex. GeoPort is a serial communications standard  
that is intended to replace the RS-232, Appletalk, and LocalTalk printer ports all in one connector in addition  
to providing real-time data transfer capability. It provides point-to-point connections between  
GeoPort-compatible devices with data transmission rates up to 4 Mbit/s full duplex and a hot-plug feature.  
Applications include connection to telephony, integrated services digital network (ISDN), digital sound and  
imaging, fax-data modems, and other serial and parallel connections. The GeoPort is backwardly compatible  
to both LocalTalk and AppleTalk.  
WhiletheSN75LBC776ispowered-off(V =0)theoutputsareinahigh-impedancestate. Whentheshutdown  
CC  
(SHDN) terminal is high, the charge pump is powered down and the outputs are in a high-impedance state. The  
driver enable (DEN) terminal sends the outputs of the differential driver into a high-impedance state with a high  
input signal. All drivers and receivers have fail-safe mechanisms to ensure a high output state when the inputs  
are left open.  
A switched-capacitor voltage converter generates the negative voltage required from a single 5-V supply using  
four 0.1-µF capacitors, two capacitors between the C+ and C- terminals and two capacitors between V and  
EE  
ground.  
The SN75LBC776 is characterized for operation over the 0°C to 70°C temperature range.
