– N EW P RODUCT I NTRODUCTION – DS7838J/B Rochester Electronics has re-introduced and continues to manufacture critically needed semiconductors with the full authorization of the original manufacturer and an attention to quality that meets or exceeds the original component. Original Manufacturer: Re-introduced by Rochester Electronics on May, 14, 2012 DS7838J/B Original Part Number: DS7838J Description: Quad Unified Bus Transceiver Package: 16 pin DIP Manufacturing Flow: /B Manufacturing Type: made from original National Semi wafers Related Devices [ by temperature / package type / speed / application ] DS7838J DS7838J/883 DS7838J/883B DS7838J/883C DS7838J/A+ DS7838W-MIL DS7838W/883 DS8838J DS8838M DS8838N HIGH-SPEED BUS TRANSCEIVER featuring four driver/receiver pairs 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.
