GeoPort Peripheral (DCE) Interface Device Uses LinBiCMOS Process Technology
descriptionThe 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
real-time data transfer 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.
While the SN75LBC771 is powered off (VCC and VEE = 0), the outputs are in a high-impedance state. Also, when
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.
