SN75159 Datasheet | Texas Instruments

description The SN75159 dual differential line driver with 3-state outputs is designed to provide all the features of the SN75158 line driver with the added feature of driver output controls. There is an individual control for each driver. When the output control is low, the associated outputs are in a high-impedance state and the outputs can neither drive nor load the bus. This permits many devices to be connected together on the same transmission line for party-line applications. The SN75159 is characterized for operation from 0°C to 70°C. logic symbol† logic diagram (positive logic) 1EN 6 1A 4 1B 5 2EN 9 2A 10 2B 11 & EN 3 1Y 2 1Z 12 2Y 13 2Z † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12. 6 1EN 1A 4 5 1B 9 2EN 2A 10 11 2B 3 1Y 2 1Z 12 2Y 13 2Z 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.
