SN75LBC773 Datasheet | Texas Instruments

description The SN75LBC773 is a low-power Lin Bi CMOS device that incorporates the drivers and receivers for a 9-pin Geo Port host interface. Geo Port bines hybrid EIA/TIA-422-B and EIA/ TIA-423-B drivers and receivers to transmit data up to four-Mbit/s full duplex. Geo Port is a serial munications standard that is intended to replace the RS-232, Apple Talk, and printer ports all in one connector in addition to providing real-time data transfer capability. The SN75LBC773 provides point-to-point connections between Geo Port-patible 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 Geo Port is backwardly patible to both Local Talk and Apple Talk.

A logic 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.
