DS8641 Quad Unified Bus Transceiver January 1996 DS8641 Quad Unified Bus Transceiver General Description The DS8641 is a 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 ground.
The bus can be terminated at one or both ends.
Low bus pin current allows up to 27 driver/ receiver pairs to utilize a common bus.
The bus loading is unchanged when VCC = 0V.
The receivers incorporate tight thresholds for better bus noise immunity.
One two-input NOR gate is include...
