    SGLS211A − OCTOBER 2003 − REVISED MAY 2008 description (continued) The SN65LBC176 combines a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, which can externally connect together to function as a direction control. The driver differential outputs and the receiver differential inputs connect internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. This port features wide positive and negative common-mode voltage ranges, making the device suitable for party-line applications. Very low device supply current can be achieved by disabling the driver and the receiver. Both the driver and receiver are available as cells in the Texas Instruments LinASIC Library. This transceiver is suitable for ANSI Standard RS-485 and ISO 8482:1987 (E) applications to the extent that they are specified in the operating conditions and characteristics section of this data sheet. Certain limits contained in the ANSI Standard RS-485 and ISO 8482:1987 (E) are not met or cannot be tested over the entire extended temperature range. logic diagram (positive logic) DE 3 4 D RE R 2 6 1 7 A Bus B schematics of inputs and outputs EQUIVALENT OF EACH INPUT TYPICAL OF A AND B I/O PORTS TYPICAL OF RECEIVER OUTPUT VCC VCC VCC 100 kΩ NOM A Port Only 3 kΩ NOM A or B Output Input 18 kΩ NOM 100 kΩ NOM B Port Only 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 1.1 kΩ NOM
