The outputs provide complementary signals with high-current capability for driving balanced lines, such as twisted pair, at normal line impedance without high power dissipation. The output stages are TTL totem-pole outputs providing a high-impedance state in the power-off condition. The SN75158 is characterized for operation from 0°C to 70°C. logic symbol‡ 1A 2A 3 5 logic diagram (positive logic) 2 1 6 7 1A 3 2 1 1Y 1Z 2Y 2A 2Z 5 6 7 1Y 1Z 2Y 2Z ‡ This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
