These devices are optimized for balanced multipoint bus transmission at signalling rates up to 30 million bits per second. The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment. 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 1A 1Y 1Z 1,2EN 2Z 2Y 2A GND VCC 4A 4Y 4Z 3,4EN 3Z 3Y 3A N PACKAGE (TOP VIEW) logic diagram (positive logic) 4Z 4Y 3Z 3Y 2Z 2Y 1Z 1Y 4A 3A 2A 1A 1 7 9 15 2 3 6 5 10 11 14 13 1,2EN 4 3,4EN 12 4Z 4Y 3Z 3Y 2Z 2Y 1Z 1Y 4A 3A 2A 1A 1 9 11 19 2 4 8 6 12 14 18 16 1,2EN 5 3,4EN 15 logic diagram (positive logic) 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 1A 1Y NC 1Z 1,2EN 2Z NC 2Y 2A GND VCC 4A 4Y NC 4Z 3,4EN 3Z NC 3Y 3A 20-DW PACKAGE (TOP VIEW) 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 1A 1Y 1Z 1,2EN 2Z 2Y 2A GND VCC 4A 4Y 4Z 3,4EN 3Z 3Y 3A 16-DW PACKAGE (TOP VIEW) Copyright 2001 − 20003, Texas Instruments Incorporated 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. †The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second).
