DS7838J/B High-Speed Bus Tranceiver

The Am7838 (and Am8838) are quad high-speed drivers/receivers designed for use in bus organized data transmission systems interconnected by terminated 120Ω impedance lines.  The external termination is intended to be a 180Ω  resistor from the bus to the +5V logic supply together with a 390Ω resistor from the bus to the ground. The Am7838 features four totally separate drive/receiver pairs per package. The 1V typical receiver input hysteresis is independent of receiver output load.
