SN75158 Datasheet | Texas Instruments

description The SN75158 is a dual differential line driver designed to satisfy the requirements set by the ANSI EIA/TIA-422-B and ITU V.11 interface specifications. The outputs provide plementary 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‡ 3 1A 5 2A logic diagram (positive logic) 2 1Y 1 1Z 6 2Y 7 2Z 3 1A 5 2A 2 1Y 1 1Z 6 2Y 7 2Z ‡ This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
