Line Drivers/Receivers DM7837/DM8837 hex unified bus receiver general description The DM7837/DM8837 are high speed receivers designed for use in bus organized data transmission systems Interconnected by terminated 120n Impedance lines. The external termination is intended to be 180[2 reSIStor from the bus to the +5V logic supply together with a 390[2 resistor from the bus to ground. The receiver design employs a built-in Input hysteresIs providing substantial nOise Immunity. Low input current allows up to 27 driver/receiver pairs to utilize a common bus. Disable Inputs provide time discriminatIOn. Disable Inputs and receiver outputs are DTL/TTL compatible. Performance is optimized for systems with bus rISe and fall times::::: lOllS.
